It was raining heavily, (sparsely), (falling to the ground like beans).

2) I treat patients and restore them to health, so I feel happy.

I donate money to the people in the disaster area), so I feel happy.

From A to B, if the speed is increased by 1 9, you can arrive 20 minutes earlier than the scheduled time, if you drive 72 kilometers at the original speed, and then increase the speed by 1 3, you will arrive 30 minutes earlier than the scheduled time. How many kilometers are A and B apart?

Solution: 20 minutes = 1 3 hours. 30 minutes = 1 2 hours.

Because the distance is certain, time and speed are inversely proportional.

Then the ratio of the original speed to the speed of the vehicle after increasing 1 9 is 1:(1+1 9)=9:10

Then the time ratio is 10:9

If the original time is regarded as the unit 1, then the time after the acceleration of 1 9 is 1x9 10 = 9 10

So the original time required is (1 3) (1-9 10) = 10 3 hours.

After the second 72 km, the ratio of the original speed to the increased speed is 1:(1+1 3)=3:4

Then the time ratio is 4:3

If the time after 72 kilometers is considered as the unit 1, then the time spent on this period is (1 2) (1-3 4) = 2 hours.

Then the original 72 km travel time = 10 3-2 = 4 3 hours.

Original speed = 72 (4 3) = 54 km/h.

A and B are separated by mu = 54 10 3 = 180 kilometers.

If not, the right to practice the state or hi me, I wish you progress in your studies.

Ask for the clothes again.

Sneakers: 360 divided by 3 = 120 yuan.

Clothes: 120 RMB.

Set a pair of sneakers for x yuan, then a set of clothes for yuan.

x+ solution: x=100 (yuan) then yuan) Answer: 260 yuan to buy a set of clothes, 100 yuan to buy a pair of sneakers.

Sneakers**: 360 (1+.)

Clothes**: sneakers***
