Question

A man covers a distance of 23km in 5/2 hours partly by foot at the rate of 5 km/h and partly by bicycle at the rate of 10 km/h find the distance covered by foot

​

Answer 1

Answer:

THE ANSWER IS 52.5km.

Step-by-step explanation:

Distance covered by foot time × distance covered by bicycle = 23 × 5/2

or, 5[(5/2) - t] + 10t = 115/2

or, 5 - 5t + 10t = 115/2

or, 5t + 5 = 115/2

or, 10t + 10 = 115

or, 10t = 105

or, t = 10.5 h

Distance travelled by foot = velocity × time = 5km/h × 10.5 h = 52.5km.
