Question

A train is running at a speed of 90 km/hr. If it crosses a signal in 10 seconds. Find the length of the train in metres.​

Answer 1

Step-by-step explanation:

90 km per hour is 25 metre per second. and 1 hour =60min = 3600 seconds. So to convert 90km/h into m/second... 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

Answer 2

Answer:

change 10 second in hour = 10/3600

or, = 1/360

now, divide 90km/h with 1/360

which is = 90× 1/360

or, = 1/4 km

which is = 250 m
