22 minutesExplanation
Let the total distance to be covered is 84 kms. Time taken to cover the distance without stoppage = 84/42 hrs = 2 hrs Time taken to cover the distance with stoppage = 84/28 = 3 hrs. Thus, he takes 60 minutes to cover the same distance with stoppage. Therefore, in 1 hour he stops for 20 minutes.Related questions
