A train 260 m long crosses a pole in 13 seconds. What is the speed of the train in km/h?
A. 5.56 km/h
B. 72 km/h✓ Correct Answer
C. 90 km/h
D. 20 km/h
💡 Solution & Explanation
To pass a pole, the train covers only its own length. Speed = 260 m ÷ 13 s = 20 m/s. To change m/s into km/h, multiply by 18/5: 20 × 18/5 = 72 km/h.
