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?
Elementary MathematicsTime, Speed and Distance
- A3 : 2
- B2 : 3
- C3 : 4
- D4 : 3
Explanation
Running towards each other for the same time, distances covered are in the ratio of speeds: AC : BC = 60 : 40 = 3 : 2.
