A train of length 218 m is running at 60 km/h. In what time (in seconds) will it cross a platform of length 282 m?

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 30.

Total distance = 218 + 282 = 500 m

Speed = 60 km/h

⇒ 60 km/hr = 60 × 5185\over18 = 50350\over3 m/sec

Time = 500503500\over{50\over3} = 30 seconds
