A train 140m long running at 60kmph. In how much time will it pass a platform 260m
long?
5 kmph
16 kmph
21 kmph
None of these
Explanation:
Distance travelled = 140 + 260m = 400m,
Speed = 60 * 5/8 = 50/3m
Time = 400 * 3/50 = 24 Seconds
Distance travelled = 140 + 260m = 400m,
Speed = 60 * 5/8 = 50/3m
Time = 400 * 3/50 = 24 Seconds
