In the middle of the road from Vasya's house to school, there is a traffic light. On Monday, Vasya caught the green light at the traffic light. On Tuesday, he walked at the same speed, but he stood at the traffic light for 5 minutes, and after that, he increased his speed by two times. Both on Monday and Tuesday, he spent the same amount of time on the way from home to school. How much?
By doubling his speed, Vasya covered half the distance in half the time. According to the condition, this took 5 minutes less than usual. This means that normally he covers half the distance in 10 minutes. And the entire journey from home to school takes 20 minutes.

## Answer

20 minutes.
