Question:

A 120 meter long train is running at a speed of 90 km/h. It will cross 230 m long railway platform in:

Options:

$4\frac{4}{5}$sec

7 sec

14 sec

$9\frac{1}{5}$sec

Correct Answer:

14 sec

Explanation:

Speed = 90 km/h

= 90 × $\frac{5}{18}$ m/sec

= 25 m/sec

Total distance to cover = 120 + 230 = 350m

Distance = Speed ×Time

Time = $\frac{350}{25}$

= 14 sec

The correct answer is Option (3) → 14 sec
