Question

300 metre long train running at a uniform speed crosses a platform in 55 seconds and a man standing on the platform in 24 seconds. what is the length (in metres )of the platform​

Answer 1

Answer:

387.5m

Step-by-step explanation:

Let length of platform be x

So, distance covered by train in 55s = 300+x            -- Equation 1

and, distance covered by train in 24s = 300m           -- Equation 2

So, speed of train = distance/time = 300/24 = 12.5m/s

Subtract equation 2 from equation 1

So, the distance covered by train in 31s = x

and, distance covered in 31s = speed*time = 31*12.5 = 387.5m
