Question

A police chases a driver. Originally, the police is 1 mile behind the driver. The speed of the police car is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?

Answer 1

a)1.5

b)2.0

c)2.5

d)3.0

e)3.5

I tried two formulas to calculate catch up time

1) catch up time when both r moving in same direction=distance between the two/Speed of Car A- Speed of Car B

=> 20/58-50 = 5/2=2.5

to drive 8 miles ahead of Car B by Car A

RT=D

58T=8

T=8/58

Total time= 2.5+8/58 = 2.63 ~=3.0

But answer is different

2) As Car A is 20 miles behind it must have started late than Car B have

so time taken by Car B will be t+x nd

time taken by Car A will be

As both are moving in the same direction ,both will travel the same distance till catch up tim

Answer 2
