Question

A train of length 250 m was moving at a
speed of 108 km/h. How much time will it
take to cross a bridge of length 350 m
​

Answer 1

Answer:

20 seconds.

Step-by-step explanation:

length is in metre so time should be in second so 108km/hr is 30 m/s

now, total distance the train needs to cover is :

250+350=600m

now, time=distance/speed

therefore, time=600/30

=20 seconds

Answer 2

Step-by-step explanation:

Total distance = length of train+length of bridge

Distance = 250+350= 600m

speed= 108km/hr= 30m/s

Time= Distance/Speed

= 600/30

= 20s (or) 1/3hr
