A person completes a journey of 72 km in 3 hours. How much time will he take to cover a distance of 288 km?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 12 hours
The person travels at the same speed all the way, so first find the speed from the given journey, then the time for the longer distance: time = distance ÷ speed.
Speed: 72 km in 3 hours, that is \(\displaystyle\frac{72}{3}=24\) km/h
Time for 288 km at this speed: \(\displaystyle\frac{288}{24}=12\) hours
