A train 240 m long passes a man running at 6 km/h in the same direction in 16 seconds. What is the speed of the train in km/h?
The train's speed is 60 km/h. It passes the man at a relative speed of 240/16 = 15 m/s, which is 54 km/h; because the man runs in the same direction, the train's speed is this plus 6 km/h.
- A48 km/h
- B54 km/h
- C60 km/hCorrect
- D66 km/h
Explanation
Relative speed = 240/16 = 15 m/s = 54 km/h. Train speed = relative speed + man's speed = 54 + 6 = 60 km/h. Answer 48 comes from subtracting 6 wrongly.

One question tells you little. A timed set on Time and Distance shows your real accuracy, how long you take and where you lose marks.
