Question

A train 120 meters long is running with
a speed of 60 km/hr. In what time will it
pass a boy who is running at 6 km/hr in
the direction opposite to that in which
the train is going?​

Answer 1

Answer:

Distance=120m

speed in opposite direction= 60+6

=66km/h

change into m/s

=66×5/18

18.34m/s

time=distance/speed

=120/18.34

=6sec
