Tiana can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. If they decide to clear the field together, how long will it take them?
The answer is D. 5 hours, due to the fact that there football field together, so adding there times they had done the football field individually, Tiana,3 hours, and Jacob 2 hours 2h+3h=5hours. hope i helped.
