Question

A train passes a telegraph post in 8 seconds and a 264 m long bridge in 20 seconds what is the length of the train

Answer 1

let speed of the train = v m/s

the length of the train = v*8 m

the total distance to be travelled while crossing the bridge = 264 + 8v

time taken to cross the bridge = 20 s

therefore 20= (264+8v)/v

by solving it we find v =22m/s

mark me brainly if I'm correct
