A train 100 m long crosses a platform 125 m long in 15 sec; find the speed of the train?

2 Answers on this Question

1. 1km is equal to 1000 meter
   Therefore 225 meter is how many km
   Then we have to cross multiply
   1km – 1000 meter
   ? – 225 meter
   0.225 km
   Then we have to apply formula
   Speed = Distance/Time
   Speed = 0.225/12 sec
   = 0.01875×3600sec
   = 67.5
   Therefore speed of train is = 67.5
