Because of their weight, how do trucks travel on grades?
- Slower downhill and faster uphill
- At the same speed uphill and downhill
- Faster downhill and slower uphill
- Faster uphill and slower on flat ground
Show answer

A truck's weight makes it speed up going downhill and slow down going uphill, so you may need to speed up to pass it downhill.
