Question

If the speed of train is 92.4 km/hr , then how many meters are covered by it in 20 minutes ?

Answer 1

The speed of the train is given as 92.4km/hr. Since the physics equations must be equated and solved in S.I system, we should convert the speed into S.I system⇒ s=92.4 x 1000m/3600sec⇒92.4 x 5/18⇒77/3. 

 Time(t)=20 min= 20 x 60 = 1200. 
From speed=distance/time⇒77/3=distance/1200⇒distance=30800m
