Answer:

The length of the train is below =

Speed of train in m/s.=108×5/18=30 m/s.

DISTANCE=speed × time

DISTANCE=30×24=720 metres

The length of the train =720 metres.

Time taken by the train to cross a bridge of length 90 m. is below=

length of the train+length of bridge

720+90=810

Speed of train =30 m/s.

810/30=27 second
