Answer:
56 kmph
Step-by-step explanation:
Let the speed of the train be x km/hr
Length of the train = 150m=
1000
150
=
20
3
km
and time taken to cross the man = 10 seconds =
60×60
10
Relative speed = (x−2) kmph
(Both are moving in same direction)
We know that,
Relativespeed
Lengthofthetrain
= Time taken to cross the man
Relative speed =
20×1
3×360
x−2=
20×1
3×360
x=54+2=56 kmph
Hence, speed of train is 56 kmph.
