A man is walking at a speed of 14 km/h. After every km, he takes rest for 7 minutes. How much time will he take to cover a distance of 7 km?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. hours.
Time = Distance/Speed
According to the question:
If a man did not rest
Time = 7/14 = 1/2 hr or 30 min
Number of times a man take rest = 7 - 1 = 6 times
Rest time of the man = 6 × 7 = 42 min
Total time = 30 + 42 = 72 minutes
Changing into hours = 72/60 = 6/5 = hours
