Barkat is travelling on his cycle and has calculated to reach point A at 2 P.M. if he travels at 10 kmph; he will reach there at 12 noon if he travels at 15 kmph. At what speed must he travel to reach A at 1 P.M. ?

Correct answer: C. 12 kmph

  • A. 8 kmph
  • B. 11 kmph
  • C. 12 kmph
  • D. 14 kmph

Explanation

The two travel times differ by 2 h, so D/10 h - D/15 h = 2 h, giving D = 60 km. Reaching at 1 P.M. requires 5 h, so the speed is 60 km ÷ 5 h = 12 km/h; 11 km/h is a likely estimate rather than the exact value.

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.
