To find how long it would take for Michael and Emon to shovel the snow together, you can use the concept of their combined work rates.Let M be Michael's work rate (driveways per minute) and E be Emon's work rate (driveways per minute).Michael can shovel one driveway in 12 minutes, so his work rate is:M = 1 driveway / 12 minutes = 1/12 driveways per minuteEmon can shovel one driveway in 36 minutes, so his work rate is:E = 1 driveway / 36 minutes = 1/36 driveways per minuteWhen they work together, their combined work rate is the sum of their individual work rates:Combined Work Rate = M + E = (1/12 + 1/36) driveways per minuteNow, find a common denominator to add the fractions:Combined Work Rate = (3/36 + 1/36) driveways per minute = 4/36 driveways per minuteSimplify the fraction:Combined Work Rate = 1/9 driveways per minuteNow that you know their combined work rate, you can calculate how long it would take for them to shovel one standard driveway together:Time = 1 driveway / Combined Work Rate = 1 / (1/9) = 9 minutesSo, it would take Michael and Emon 9 minutes to shovel all the snow of a standard driveway together.
