Question

A 90metres long train is running at a speed of 54 km/hr if it 30 seconds to cross a platform. Find the length of the platform?​

Answer 1

Answer:

Train velocity = V

= 54 km/hr

= 15m/s

Distance = S

= 90 m

Time = T

= ?

Using formula,

S = V × T

or, T = S/T

or, T = 90m ÷ 15m/s

or, T = 6 seconds.
