The distance between two points (A and B)is 110 km. X starts running from point A at a speed of 60 km/hr and Y starts running from point B at a speed of 40 km/hr at the same time. They meet at a point C, somewhere on the line AB.What is the ratio of AC to BC ?

A) 3:02

B) 2:03

C) 3:04

D) 4:03

Correct Answer:
A) 3:02

Description for Correct answer:

Let the time when A and B meet be 't' hr

So distance travelled by A in t hr = 60 t km

and distance travelled by B in t hr = 40 t km

So AC = (60 t) km and BC = (40 t) km

AC:BC=60t:40t = 6 : 4 = 3 : 2
