A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?
Correct answer: B. 89 Sec
- A. 80 Sec
- B. 89 Sec
- C. 90 Sec
- D. 95 Sec
Explanation
The train's speed is 240 m ÷ 24 s = 10 m/s. To pass the platform, it must cover its own length plus the platform length: 240 m + 650 m = 890 m, so time = 890 m ÷ 10 m/s = 89 s. The likely mistake is choosing 90 s by rounding the calculated time.

About Time, Speed and Distance
Problems relate distance, speed and time through the formula distance = speed × time, including unit conversion, average speed, relative speed and motion in opposite or the same direction. Questions may involve trains, boats and streams, where the effective speed changes, so average speed must not be confused with the simple average of two speeds.
