Question

A train is running at a speed of 60 km per hour calculate the speed of train in metre per second

Answer 1

To convert a value from km/hr to m/s

1km =1000m

1 hr=60mins*60secs

1hr=3600secs.

Now km/hr=1000m/3600s

1km/hr=10 m/36s

1km/hr=5m/18s.

Answer 2

Answer:

1 km = 1000 m

1 h = 3600 sec

so, 60 × 3600/1000

60 × 18/5

= 216 km/h
