4-53.

Luis rides his skateboard at the same speed all the way home. It takes him ten minutes to get there.

Corinna jogs along at the same speed until she reaches a hill, and then she slows down until she finally stops to rest.

Sergei is talking with his friends at the donut shop when he realizes that it is almost time for math class. He runs toward school, but he slows to a walk when he hears the bell ring and realizes that he is already late. He sits down in class four minutes after he left the donut shop.
