Asked by Brody

The distance between Town A and Town B was 210 km. At 9:20 P.M., a bus set off from Town A to Town B and a car left from Town B to Town A. The average speed of the bus was 60 km/h, and the average speed of the car was 80km/h.

a) Calculate the time at which the car passed the bus.



b) How far had the car traveled when it passed the bus?
Answered by Reiny
When they meet, they both would have traveled the same time.
Let that time be t hrs
so 60t + 80t = 210
140t = 210
t = 1.5 hrs
