The speed of the train in km/hr is 42 km/hr
- Speed is defined as rate of change of distance traveled.

- The S.I unit of speed is m/s.
PROBLEM:
- Given,
Distance traveled = 140 m
Time = 12 s
Speed = 140/12
= 35/3 m/s
- To convert m/s into km/hr, we need to multiply with 18/5
Speed = km/hr
= 630/15 km/hr
= 42 km/hr
