A man walks at a speed of 8 km/h. After every km, he takes a rest for 4 minutes. How much time will he take to cover a distance of 6 km?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 65 minutes
Let's distribute the 6 km journey,
1km then rest + 1km then rest + 1 km then rest + 1 km then rest + 1 km then rest + 1 km
6km + 5 × rest.
Total time = (6/8) × 60 + 5 × 4
= 45 + 20= 65 minutes.
