Question

Car A and Car B are approaching each other from two places Town X and Town Y 210 km apart, running at 50 km/h and 55 km/h respectively.
A) How long will it take them to meet?
B) How far away is their meeting place from Town X?

Answer 1

A) Let the time taken for the two cars to meet be = x hrs
Then car A has travelled distance = 50x
Car B has travelled distance = 55x
50x + 55x = 210
105x = 210
x = 210/105
x = 2

so the cars meet after travelling 2 hours

B) Car A started from Town A and in 2 hours it would have covered a distance of 2*50 = 100 km
So their meeting place is 100 km from town A
