A train running at a speed of 60 km/h crosses a pole in 9 seconds. What is the length of the train?

by

A. 140 m
B. 160 m
C. 150 m 
D. 120 m

🧠 Explanation:

A train at 60 km/h crosses a pole in 9 seconds, so its length is 150 meters. Convert speed to m/s (60 × 1000 ÷ 3600 = 50/3 m/s), then length = speed × time = 50/3 × 9 = 150. This helps students learn motion calculations.
