Question

300 metre long train crosses a platform in 39 seconds while it causes a signal pole in 18 seconds what is the length of the platform

Answer 1

Answer:

350 m

Explanation:

Distance travelled by train to cross the signal pole = Length of train = 300 m

Speed of train = Distance / Time

= 300 m / 18 s

= (100/6) m/s

Length of platform = L

Distance covered by train to completely pass the platform = 300 m + L

Distance = Speed × Time

300 m + L = (100/6) m/s × 39 a

300 m + L = 650 m

L = 650 m - 300 m

L = 350 m

Answer 2

Answer:

350

Step-by-step explanation:

Let, Length of the Platform = x

Speed = 300/18

           = 50/3 m/s

Total Distance = 300 + x

Distance/Time = Speed

or, ( 300 + x )/39 = 50/3

or, 3( x + 300 ) = 1950

or, x = 350
