A 132 meter long train passes an electic pole in 6 second. The speed of a train is?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 79.2 km/h
To pass a pole the train covers exactly its own length, so its speed is 132 ÷ 6 = 22 metres per second.
Converting, 22 × 18/5 = 79.2 km/h.
