A train 600 m long crosses a pole in 15 seconds. What is the speed of the train in km/h?
A. 40 km/h
B. 144 km/h✓ Correct Answer
C. 162 km/h
D. 11.11 km/h
💡 Solution & Explanation
To pass a pole, the train covers only its own length. Speed = 600 m ÷ 15 s = 40 m/s. To change m/s into km/h, multiply by 18/5: 40 × 18/5 = 144 km/h.
