**MathMate**, Saturday, June 7, 2014 at 6:41amConvert speed to m/s:

36 km/h = 36/3.6=10 m/s

In calculating train crossing bridges, we have to remember that after the head of the train has crossed the bridge (800 m), the remainder of the train is still on the bridge. So to*completely*cross the bridge, the time is what is takes to travel 800+100 metres.

Time required

= (800+100)m /10 m/s

= 90 s
