At 3; 43 don finished baking 48 doughnuts. He started at 3:27 pm at his baking speed what time after 3:43 will it be for him to finish another 5 dozen doughnuts

5 dozen = 60 doughnuts

3; 43-3; 27 = 16

So it took him 16 minutes for 48 doughnuts

16:48=0,3 so one doughnut takes him 30 seconds

60*0,3=19,99=20 so it takes him about 20 minutes for 5 dozens of doughnuts

So it'll be 4; 03
