Question

a train is moving at the speed of 180 km per hour . find the distance covered by the train in 5 seconds

Answer 1

Speed of train = 180 km/hr = 180 × $\frac{1000}{60 X 60}$ m/s

speed of train = 50 m/s

distance = speed × time.

distance = 50m/s × 5s

∴ Distance covered by train in 5 sec = 250 m

Answer 2

Answer:

3600second=1hr

1 sec=1/3600hr

5sec=1/3600×5=1/720hr

In 1 hour train covers 180 km.

In 1/720 hour train covers 180×1/720=1/4=0.25km

Hence, distance covered by train in 5 second=0.25km
