Question

Find the time taken by a train 150 m along, running at 60 km \hr in crossing a man standing on the platform ?

Answer 1

Speed of train$=60$ km/h $=60\times \frac{5}{18}=\frac{50}{3}$ m/s

Distance to be covered by train$=150$m

We know speed $=\frac{Distance}{Time}$

Time taken by train to cross the man on platform

$=\frac{150}{50}=9$sec

[Time taken $=9$ sec].
