Marks: +1, -0

How many seconds will a train 120 metres long running the rate of 36 km/hr take to cross a bridge of 360 metres in length?

Solution:

Total distance = Length of train + Length of bridge

= 120 + 360 = 480 m

Speed

=36km{/}h={36×1000}/3600=10\m{/}\sec

So time

={\Distance}/{\Speed}=480/10=48 \sec
