A family drives 400 milles in 8 hours. Explain how the acceleration of their car changed?

Answer 1

There are many ways to go 400 miles in 8 hours. All you need to do is average 50 mph.

In the real world, you have to stop at traffic lights and stop signs; slow down when there is a slower driver ahead of you, and speed up to pass.

That is a crazy question.
