Both car A  and Car B leave school when a stopwatch reads zero. Car A travels at a  constant 75 km/h, and car B travels at a constant 85 km/h

a. Draw a position- time graph showing the motion of both cars. How far are the two cars from school when the stopwatch reads 2.0h? Calculate the distances and show them on your graph.

b. Both cars passed a gas station 120 km from the school. when did each car pass the gas station ? Calculate the times and show them on your graph.
