Answered

A man walks at speed of 4 km/hr. and runs at the speed of 8 km/hr. How much time will man require to cover a distance of 24 kms if he completes half of his journey walking and the other half by running?

- 3 Hrs.
- 4.5 Hrs.
- 12 Hrs.
- 5 Hrs.

Best answer

**Answer: (b) 4.5 Hrs.**

**Explanation:-
Given-
**A man walks at speed = 4km/hr.

and runs at speed = 8km/hr.

Total distance = 24km, then half distance = 24/2 = 12km

He covered half distance by walking at speed 4km/hrs = 12/4 = 3hrs.

He covered half distance by running at speed 8kh/hrs = 12/8 = 1.5hrs.

Hence, he time taken covered half of his journey walking and other half by running = 3 + 1.5 = 4.5hrs.
