What was the total distance for trip, Physics

Assignment Help:

A cab driver in a hurry is sitting at a red light. When the light turns green she rapidly accelerates for 3.50 s at 6.80 m/s2.

The next light is still red. She then slams on the brakes, accelerating at a rate of -9.60 m/s2 before coming to rest at the stop light.

What was her total distance for this trip?
