Question

a train passes a pole in 10 second at the speed of 36km/ h then length of the train is​

Answer 1

Step-by-step explanation:

As we have given,

train passes a pole in 10 second

( time) = 10 sec

the speed of train is 36 km / hr

(speed) = 36km /hr

= (36 x (10³)m )/(60 x 60)s

=( 36 x 10 m) /36s

= 10m / sec

the length of train = distance

we know,

speed = distance / time

distance = speed x time

= 10 x 10

= 100 m

therefore the length of train is 100m
