Two cars A & B, each moving with constant acceleration, are travelling in the same
direction...? ...along the parallel lanes of a divided road. When A passes B, the speeds are 64 and 48km/h respectively. Three minutes later, B passes A, travelling at 96km/h. Find:
a) the distance travelled by A and B at this instant (since they first passed) and the speed of A
b) the instant at which both are moving with the same speed, and the distance between them at this time
I tried drawing a velocity-time graph, and got mightyly connfused!!!!
Please show working, thanks!!
I copied it word for word from the textbook, i read it as B travelling at 96
if it helps, the answer is
a) 3600m, 80km/h
b) 90 sec after A passed B, 200m
