Question

A train is running at a speed of 90 km/hr, crosses a pole in 10 seconds. The length of the train is ?
please help. ​

Answer 1

Answer:

250 m

Step-by-step explanation:

90 km per hour is 25 metre per second.

1km =1000 m

and 1 hour =60min = 3600 seconds.

So to convert 90km/h into m/second...

90*(1000/3600)= 25 m/s (approx)

So if the train takes 10 seconds to cross a pole while running at 90 km/h then the length of the train is 25 * 10 which is 250 m.
