A traveller goes from City P to Q at 24 km/h in 5 hours. By how much should the speed be increased to complete the journey in 3 hours?
- 16 km/h
- 20 km/h
- 24 km/h
- 28 km/h
Correct answer: 16 km/h
Solution
The distance between the cities is $24 \times 5 = 120$ km. To cover 120 km in 3 hours, the required speed is $120/3 = 40$ km/h. So the increase in speed is $40 - 24 = 16$ km/h.
