Winston is a 26 minute walk!

First of all, it should be clear that the time of the car and the person are not at the same time, and it is obvious that the car starts earlier!

Let's say he usually takes the car home at the time of t

The time it takes for the car to meet today is the T-car.

The time it takes for people to go from departure to meeting today is T people.

First of all: for the car, he left 30 minutes late, but only 22 minutes later than usual, that is, he saved 8 minutes on the road than usual.

In this way, the formula can be obtained: 2t-2·t car = 8 (2t is the time to consider the round trip).

Secondly: for the person, the time he took today was (t man + t car) because he was 22 minutes later than usual.

In this way, the formula can be obtained: (t person + t car) -t = 22 The two formulas are combined to get t person = 26 minutes.

If Winston had been waiting at the station, the driver would have arrived half an hour later because he had left half an hour later than usual. That is, Winston will wait at the station for half an hour to get home when his car arrives, so that he will arrive home half an hour later than usual. Now Winston arrives home only 22 minutes later than usual, which is the 8 minutes that the driver would have spent traveling from where he met President Winston now to the train station and back to that location if the president had been waiting at the train station.

This means that if the driver drove from the place where he now met the president to the train station, the time taken each way would be 4 minutes. So if Winston was waiting at the train station, in another 4 minutes his car would have arrived. That is, if he is waiting at the train station, then he has also been waiting for 30-4=26 minutes.

But President Winston, who was afraid of guilt, did not wait, and he hurried to the road, spending all 26 minutes on foot.

So, Winston walked for 26 minutes.

That's a great question.

Winston walked 41 minutes.

So, 9 people can get up to 4 stickers each.

Isn't that all about using 41 9? The result is equal to four, and each student can get four stickers on average, but there are still 5 left, so he will keep it to himself. Because 4 9 = 36! Then, 41-36 = 5

Solution: Let it be t, so the total number of questions is 5t

The time to do 10 questions at the original speed is: 10 5 = 2 hours.

60% increase in efficiency

The speed is 5 (1+60%)

5*(8 5)=8 hours, add 6 questions to the remaining number of questions, and the completion time is t-3-2=t-5

The remaining number of questions is 5t-10

So 5t-10+6=8(t-5), 36=3t is solved: t=12, so that 5t=5*12=60

So according to the original practice, the number of questions to complete is 60 and it takes 12 hours.
