Multiple choice

A train 280 m. long is moving at a speed of 60 km./hr. What is the time taken by the train to cross a platform 220 m. long? एक 280 मी. लम्बी रेलगाड़ी 60 किमी./घं. की रफ्तार से चल रही है। किसी 220 मी. लम्बे प्लेटफार्म को पार करने में उस रेलगाड़ी को कितना समय लगता है?

  1. 45 seconds/सेकेण्ड

  2. 40 seconds/सेकेण्ड

  3. 35 seconds/सेकेण्ड

  4. 30 seconds/सेकेण्ड

D Correct answer
Explanation

Total distance to cross = train length + platform length = 280 + 220 = 500 m. Speed = 60 km/hr = 60 × (5/18) = 50/3 m/s. Time = Distance/Speed = 500 ÷ (50/3) = 500 × 3/50 = 30 seconds. This is a standard train-platform problem requiring unit conversion.
