A person walks 40 km at a speed of 5 km/hr, then runs 30 km at a speed of 10 km/hr. What is the ratio of walking time to running time?
8 : 3
Walking time: \(\dfrac{40}{5} = 8\) hours. Running time: \(\dfrac{30}{10} = 3\) hours.
Ratio of walking time to running time: \(8:3\).
Hence, the ratio of walking time to running time is 8:3.
