Question

A 200m long train crosses 400m bridge with a velocity of 36km/h. Find the time taken by the train to cross the bridge

Answer 1

Step 1, Given data

Length of the train = 200 m

Length of the bridge = 400 m

Velocity of the train = 36 km/h = 10 m/s

Step 2, Find the time taken

For the complete crossing of the bridge, the train has to travel a total distance equal to 400 m + 200 m = 600 m

We know,

$Timetaken=\frac{Totaldistance}{Velocity}$

Putting all the values

$Time=\frac{600}{10}=60sec$

Hence the time taken by train to cross the bridge is 60 sec or 1 min.
