Piyush is running at the speed of 8 km/hr and he stops for 5 minutes to take rest at the end of every third km. What will be the time taken by Piyush to cover a distance of 56 km?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 8 hr 30 minutes
Time = Distance/Speed
Total time = time taken to cover a distance + Rest time
Time taken to cover a distance = 56/8 = 7 Hrs.
Total rests = 18 ( till 54 km , 54/3 = 18)
Rest time = 18 × 5 = 90 mins i.e 1hr 30 mins
Total time = 7hrs + 1 hr 30 mins = 8hr 30 mins
