Physics

A car sits in an entrance ramp to a freeway, waiting for a break in the traffic. The driver sees a small gap between a van and an 18-wheel truck and accelerates with constant acceleration along the ramp and onto the freeway. The car starts from rest, moves in a straight line, and has a speed of 16.0m/s when it reaches the end of the ramp, which has length 118m.

A. What is the acceleration of the car?

B. How much time does it take the car to travel the length of the ramp?

C. The traffic on the freeway is moving at a constant speed of 16.0 . What distance does the traffic travel while the car is moving the length of the ramp?

I got 14.75 to be the time it took him to travel the ramp but that isn't the correct answer.

I'm not sure how to set up for the other parts.
