A section of the road is divided into three sections: uphill, flat and downhill, and the distance ra

The whole journey is 2 hours and 120 minutes, and the ratio of the three periods of time is 6:5:4, and the total time of these three periods is 15 parts, each of which is 120 15 = 8 minutes, so the three periods of time are 48 minutes, 40 minutes and 32 minutes, and then the time is converted into hours are 48 60 = 4 5 hours, 2 3 hours and 8 15 hours, and then multiply the time on the flat road by the speed of the flat road to get 8 kilometers of the flat road distance.

The whole journey can be divided into 13 parts, and the flat road accounts for 3 13 parts, so the length of the whole journey should be 8 kilometers divided by 3 13 equals 104 3 kilometers, which is about 35 kilometers.

The ratio of the length of each section is 2:3:4, and the uphill distance accounts for 2 (2+3+4)=2/9 of the total distance, and the uphill distance is 36 2/9 = 8 kilometers.

You can know the uphill time 8 4 = 2 hours.

The ratio of time spent on these three journeys is 4:5:6

The ascent time is 4 (4 + 5 + 6) = 4 out of 15 rows and 2 4 out of 15 = hours for the complete journey.

Uphill:Flat:Downhill Time Ratio is 6:5:4? Then the answer should be:

The time taken on the flat road is 5 (6 + 5 + 4) = 1 3, the whole journey is 2 hours, the flat road time is 2 3 hours, the speed is 12 kilometers per hour, the flat road distance = speed = 8 kilometers, the flat road accounts for the whole journey 3 (2 + 3 + 5), so the total length is 80 3 kilometers that is 26 and 2 3 kilometers.

The ratio of time spent on the three journeys is 6:5:4, and the whole journey takes 2 hours, so it takes 6*2* (6+5+4)=hours on the flat road.

So the distance of the flat road is 12*km. The journey is kilometers long.

The total length of the journey is 24 km.

So the uphill distance is 24*1 (1+2+3)=4 km, and it is known that the speed of his uphill is 3 km/h.

So the uphill time is 4 to 3 hours.

The uphill time is 4 (4+5+6)=4 15, so the total time is.

4 3) (4 15) = 5 hours.

Uphill=24 (1+2+3) 1=4 km.

Uphill time = 4 3 = 4 3 hours.

Journey time = 4 3 4 (4 + 5 + 6) = 5 hours.

A section of the road is divided into three sections: uphill, flat and downhill, and the ratio of the length of each section is 1:2:3, and the speed ratio of each section of the road is 4:

5：6。It is known that the speed of his ascent is 3 kilometers per hour, and the total length of the uphill road is 5 kilometers.

Solution: Let the speed of uphill, flat and downhill be 4x, 5x, and 6x; 4x=3km h, so x=(3 4)km h;

The uphill speed is 4 (3 4)=3 km h, the flat speed is 5 (3 4)=(15 4) km h, and the downhill speed is 6 (3 4)=(9 2) km h

Then set the length of uphill, flat and downhill roads as y, 2y, and 3y, and it is known that y=5km, so the flat land is 10km long and the downhill is 15km

Therefore, it takes time for the person to complete the journey: t=5 3+10 (15 4)+15 (9 2)=5 3+(8 3)+10 3=23 3 (hours).

The total length of the road is 5 km: the total length of the Deping Road is 10 km, and the total length of the downhill road is 15 km.

The speed from the uphill slope is 3 km/h: Deping Road 4 3 5 km/h, downhill 4 3 6 km/h.

Total time 5 3 + 10 (4 3 5) + 15 (4 3 6) = do the math yourself haha.

Solution: From the meaning of the question, it can be seen that the whole journey of the flat road is 5 * 2 = 10 kilometers, the whole downhill journey is 5 * 3 = 15 kilometers, the speed of the person walking the flat road is 3 * 5 4 = kilometers and hours), the speed of the person walking downhill is 3 * 6 4 = kilometers and hours), the time of the whole journey of the person is: 5 3 + 10 (hours).

Answer: The time for this person to complete the journey is 23-3 hours.

The total length of the road is 24 kilometers, and the length ratio of the three sections is 1:2:3, which can be calculated to be 4 kilometers, 8 kilometers and 12 kilometers respectively.

The uphill speed is 3 km/h, so it takes 4 to 3 hours.

The time ratio of the three sections is 4:5:6, so it takes 5 3 hours for the flat slope and 6 3 hours for the downhill slope.

So the total duration is 4 3 + 5 3 + 2 = 5 hours.

Uphill distance: 2 (2+3+4)*36km=2 9*36km=8kmFlat road distance: 3 9*36km=12km

Downhill distance: 4 9*36km=16km

Let the flat speed be v2 and the downhill speed be v3, then: 2 4:3 5:4 6=4:v2:v3

Solution: v2 = 24 5km h

v3=16/3km/h

So the time is t=8 4+12 (24 5)+16 (16 3)=2+

A: It takes hours to complete the journey.

Since the distance ratio of each section is 2:3:4 in turn, the length of each section can be set to be 2x, 3x, and 4x, and the total length of the distance is 36 kilometers.

2x+3x+4x=36

x = 4 km.

So the uphill distance is 2x=2*4=8 km.

And because the uphill speed is 4 km/h, the uphill time is 8 4=2 hours, because the time ratio of the three sections is 4:5:6, so the time taken to complete the journey is 2 4 * 4 + 5 + 6) = hours.

The ratio of the speed of each segment is 1 4:2 3:3 6

The uphill speed is 3

Then the flat slope speed is 2 3 times 3 divided by 1 4 = 8, and the downhill speed is 3 6 times 3 divided by 1 4 = 6

The total length of the journey is 60 km, and the length of the uphill slope is 60*1 (1+2+3)=10

The length of the flat slope is 60 2 (1+2+3)=20

Downhill length 60 3 (1+2+3)=30

The whole journey time is 10 3 + 20 8 + 30 6 = 65 6 hours.

60 6 = 10, we know that the uphill slope is 10 km, the flat slope is 20 km, and the downhill slope is 30 km.

t=10 3 is the uphill time.

Total time elapsed t=t (4 15) = hours.

60 1:2:3=10:20:30

Ascent time : 10 3

Journey time = (4+5+6) 4*10 3=50 4=hours.

Solution: The flat road walked 5x5 (6+5+4)=5 3 hours, and the flat road has kilometers, so.

The journey is in kilometers.

According to the topic, there are three sections of uphill, flat road and downhill, and the length of each section is 2x, 3x, and 5x (unit km).

The time for each copy is 5 (6+5+4)=1 3

Then the length of the flat road is 3x=1 3*

x = full journey.

It takes 5 to 3 hours to walk the flat road, so the flat road is a kilometer long and the whole journey is 25 kilometers.

The length of the journey is 50km, and the ratio of the length of each section is 1:2:3. Flat. The lengths of the lower three paragraphs are:

He went uphill at a speed of 3 km/h

So the time it takes him to go uphill is (50 6) 3 = 50 18 = 200 72, because the ratio of the time spent on each section is 4:5:6

So the time to walk on the flat section is (5 4) * (50 18) = 250 72 and the downhill time is (6 4) * (50 18) = 300 72, so the total time is 200 72 250 72 300 72 = 750 72 = 125 12 = hours.

2.The total length of the road is 50km

Therefore, the uphill, flat, and downhill slopes are 25 3, 50 3, 25km, and the speed is 3km h when going uphill, so it takes 25 9h to go uphill, so it takes 25 9 (1+5 4+6 4)=25 3 5 4=125 12h

Let the first section of the journey be x, then there is x+2x+3x) set the uphill time to be 4t, then there is 4t=x) total time t=4t+5t+6t)

x=10m from (1).

t=5 6s from (2).

From (3) t=15*5 6=hours.

It took the man an hour to complete the journey.

60/6=10km

10 3 = 1/30 hours.

10 13 4 = 5/6 of an hour.

Five-sixths 5 = twenty-five sixths of an hour.

5/6 6 = 5 hours.

Ten thirds + twenty-five sixths + 5 = twelve and a half hours.
