Question

A train travelling at the uniform speed takes 10 hours to cover a distance of 1200km.express the speed in km/hour and m/sec

Answer 1

Given,
Distance = 1200km
Time = 10 hours
So, Speed = Distance/Time = 1200/10km/hr = 120km/hr
And, 120km/hr = 120*5/18 m/s =100/3 m/sec = 33.33m/sec

Answer 2

Km/hr=
1200/10
=120 km/1hr
In
M/sec
1hr=60*60sec
1km=1000m
So
120*1000/60*60
=120000/3600
=33.333app.
=33.333m/sec
