Distance = 120 m = 0.12 km
Time = 5 sec = 5 / 60*60 = 1/720 hours
Speed = Distance /Time
= 0.12 ÷ (1/720)
= 0.12 * 720
= 86.40
= 86.4 km/h
Time = 5 sec = 5 / 60*60 = 1/720 hours
Speed = Distance /Time
= 0.12 ÷ (1/720)
= 0.12 * 720
= 86.40
= 86.4 km/h

Speed of the train in m/s = (120/5) m/s
= 24 m/s.
Speed of the train in km/h = 24(18/5) km/h
= 86.4 km/h.

= 24 m/s.
Speed of the train in km/h = 24(18/5) km/h
= 86.4 km/h.
