Question

A train is 100m long.find the time it takes to cross a bridge,500m long,when moving at a uniform velocity of 5km/hr.

Answer 1

★ Ello ★

here is your answer !!

length of train =. 100 m

length of bridge = 500 m

distance travelled = length of train + length of bridge


=> ( 100 + 500 ) m

=> 600 m


velocity => 5km / h

therefore,

5 × 5 / 18 m / s

= >. 1.38 m / s


to calculate :-

time taken.


t = d / v

=>. 600 / 1.38


t => 434 .7 second


or 7.2 min


hence , your answer is

★ 7 .2 min ★


hope it helps you dear !!
