Question

A man walks at a speed of 8 km / h. After every kilometre, he takes a rest for 4 minutes. How much time will he take to cover a distance of 6 km?

• A. 70 minutes
• B. 60 minutes
• C. 65 minutes
• D. minutes69

Answer 1

Answer:

C. 65 minutes

Solution: 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.
