Question

a train 100m long is to cross a river bridge of length 800 metre what time will it take to cross the bridge give the train moves with the constant speed of 36m/seconds?
note:;don't convert the time .. the time is already in seconds ​

Answer 1

Total distance required for the train to cross the bridge is,

d = (100 + 800) m = 900 m

Hence the time taken to cross the bridge is,

t = 900 / 36 = 25 s.

Answer 2

Answer:

go 1 m by 36second

go 800 m by 36×800=28800
