Question

a train is running at a speed of 64 km/hr passes an electric pole in 16 seconds how much time will it take to cross the platform 256 M long?​

Answer 1

Step-by-step explanation:

the length of the train =covered distance in 16 sec

in 16 sec the train covered the distance

64000×16/3600 m

=640×4/9 m

=2560/9 m

here 64 km=64000 m and 1 hour =3600 sec

to cross the platform 256 m long the train covered the distance =(256+2560/9) m

=256(1+10/9) m=256x19/9 m

time take by the train

=3600x256x19/9x64000 sec

=36x256x19/9×640 sec

=16x19/10 sec

=304/10sec

=30.4sec
