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

Yes after 2 or 3 hours B willcatchA

Answer 2

Time on which A started = 5:00 PM
Speed = 5 km /hr
Time in which he'll cover 5 km
= 1 + 5
=6:00 PM
Time on which B started = 5:15 PM
Speed = 10km/hr = 5 km in 30 minutes
Time in which he'll cover 5 km
=15 + 30
=45
=5:45PM
Yes,he'll catch him in 5:45 PM
Hope it helps...!!!
