Question

2 guys, A and B are standing at the same point X at 5:00 PM. A walks at 5KM/HR, B is on a cycle and goes at a speed of 10 KM/HR. A starts from point X at 5:00 PM, B starts in the same direction at 5:15 PM. Will B catch up with A? If yes, at what time?

Answer 1

Time when A starts = 5:00
Speed= 5kmph
Time on which one km is covered= 6:00
Time when B start = 5:15
Speed= 10kmph
One km covered in 30 minutes.
Time when both meet= 30 minutes after the travel of B= 15+30
= 5:45
