Answer 1

Hey.

Here is the answer.

_________________________

Length of train=360m=0.360 km
speed of train =60km/h
speed of Aryan=6km/h
so, relative speed of train w.r.t. Aryan =60-6=54 km/h as both are moving in the same direction.

as time= distance/speed
so, time=0.360/54=360/54000=2/300 hr= 1/150 hr

as 1hr= 60 minutes
so, 1/150hr =60×1/150 minutes=2/5 minute

= 2/5×60 sec= 24 sec
