Question

a train 100m long is to cross a river bridge of length 800m. what time it take to cross the bridge ?velocity of train is 36km/h.

Answer 1

Convert 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 <i>completely</i> cross the bridge, the time is what is takes to travel 800+100 metres.
Time required
= (800+100)m /10 m/s
= 90 s

Answer 2

(a)800 m. (b)1000 m.(c)1500 m.(d)2600 m.

Answer 3

1. A train pusses over a 200 M long bridge in 10 sec. The length of the train is 100m. The speed of the train is.? Ans.bridge length = 200m. Train - 100m time - 10 sec - none
300m

- 300/10=30 M/s
Answer...30 M/s

Answer 4

A train 100m long is to cross a river bridge of length 800m.what time will it take to cross the bridge ? Given that the train moves with a contant velocity of 36 km / h
