Best answer
Correct Answer - Option 3 : 65 minutes

Given:

Speed of man = 8 km/hr.

Distance = 6 km

Time of rest = 4 minute

Formula used:

Speed = Distance/Time

Calculations:

⇒ 8 km distance covered by man = 1 hours

⇒ 8 km distance covered by man = 60 minutes

⇒ 1 km distance covered by man = 60/8 minute + 4 minute (rest )

⇒ 5km distance covered by man = 300/8 minute + 20 minute

⇒ Last 1 km distance = 60/8 minutes

⇒ Total time taken by him = (300/8) + (60/8) + 20

⇒ Total time taken by him = 65 minutes

∴ It will take 65 minutes to cover a distance of 6 km.
