Question

If a distance travelled by train is 495km in 4hours 30minutes,what is its speed

Answer 1

4 hours 30 minutes = 4.5 hours

Speed = Distance / Time
= 495 km / (4.5 hours)
= 110 kmph

Speed of train is 110 kmph

Answer 2

Distance = 495 km
Time = 4hours 30 minutes = 4.5 hours
Speed = Distance / Time
Speed = 495 km / 4.5 hour
= 110 km/h
In SI unit [i.e. in m/s ] is 110 km/h * 5/18 = 30.5555... m/s = 30.6 m/s
