Question

A man complete a distance in 9 hours first in 4km per hour and rest is 5 km per hour

Answer 1

Answer:

Step-by-step explanation:

Let time taken by first speed = x

Time taken by second speed = 9-x

Distance = speed × time

Distance1 = 4×x

= 4x

Distance2 = 5(9-x)

= 45-5x

Total distance = 4x + 45-5x

= 45-x km ans
