How many miles does the detour add to the farmer’s commute into town? A) 8 miles B) 10.5 miles C) 12 miles D) 15.7 miles
We are given with 29 miles distance in a straight travel 21 miles up to an intersection, if the farmer has to travel 5 miles to the right, then 10 miles left and 5 miles left, the total distance would be 41 miles The difference in the distance is 41 miles - 29 miles = 12 miles<span />
