A car covers a distance of 624 km in 6 hours. Find its speed.

  • A.104 kmph
  • B.140 kmph
  • C.104 mph
  • D.10.4 kmph

Answer: A

\[ v = \frac{\text{distance}}{\text{time}} = \frac{624}{6} = 104 \text{ kmph} \]

The mph option is a units trap: the distance is given in kilometres, so the speed must be in kilometres per hour.
