Question

A train starts from rest and covers a distance of 450 m in 2 min . calculate the speed of train in ( 1 ) m/s ( 2 ) km/h

Answer 1

Given , distance = 450m...
=0.45km...
Time taken =2min
=120sec
=2/60hours=1/30h

Therefore, speed = distance travelled/time taken
=450/120=3.75m/s
And , 0.45/(1/30)
=0.45×30=13.5km/h
