Question

A train crosses a pole in 18 seconds where as crosses a platform 220 metre long in 29 seconds. Find the speed of train

Answer 1

Answer:

20m/s

Step-by-step explanation:

let length of the train be x

time taken for the train to cross a pole is 18 seconds

i.e, time taken for the train to cross its own length(x) is 18 seconds

time taken for the train to cross a platform of length 220 meters is 29 seconds

x+220=29sec

29-18=11

the train takes 11 seconds to cross the platform

and the remaining seconds are to cross its own length

11 -> 220

18 ->x

=>   11*x=220*18

x=360

speed=distance/time

speed=360/18=20m/s
