Question

135 M long train is travelling at a speed of 62 km h dot A man is running at 8 kilometre in the same direction in which the train is moving in how many seconds will the train cross the man​

Answer 1

Answer:

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.
