Question 56
A train 240 meters in length crosses a telegraph post in 16 seconds. The speed of the train is?
Solution
Length of Train = 240m
Time taken to cross = 16secondsÂ
We know that speed = Distance /TimeÂ
so speed of train =Â $$\frac{240}{16}\ $$m/s=15m/secÂ
=Â $$15\times\ \frac{18}{5}=54$$km/hr
