Question

Example 4 A 270 m long goods train is
running at 40.5 km/h. How much time
will it take to cross a tree?​

Answer 1

Answer:

We know that speed = (distance /time)….

In this case the distance is length of the train , so on rearranging above formula we get

Time=(length/speed)

So

=(270)/(40.5*(5/18)) conversion of speed from kmph to mps since length is in meters

So the answer is 24 sec
