The speed of a train is 88 km/h. How much time will it take to cross a 180 m long platform if length of the train is 150 m?

$13\frac{1}{2}s$

To convert km/h into m/sec

88 km/h x \(\frac{5}{18}\) = \(\frac{220}{9}\) m/sec

$\text{Total length}=\text{Length of Train}+\text{Length of Platform}$

Total length=150 m+180 m=330 m

We know that ,

Time = \(\frac{Distance}{Speed}\)

= \(\frac{330 × 9}{220}\)

= \(\frac{27}{2}\)

= 13\(\frac{1}{2}\) second
