Question

a train 80 m long is running at a speed of 45 kilometre per hour in what time will it pass 220 M long platform

Answer 1

Hola

Here's your answer -

Given -

Train's length - 80m

Speed = 45km/hr

Platform length = 220m

To find - Time it will take to pass the platform

Calculation -

Total distance = 220m + 80m

= 300m = 0.3 km

It's necessary to make the S.I units same.

Speed = distance/time

Let the time be t

45 = 0.3/ t

Therefore,

time = Speed/ distance

= 45/0.3

= 160 seconds
