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?

First, combine all the hours they can clear the football field, 3 hours by Tiana plus 2 hours by Jacob, a total of 5 hours. Then get the average hours that it would take them to clear a football field by dividing 5 hours by 2. So, it will take them 2.5 hours to clear the football field together.

i only know the sequence of arithmetic it adds the first is 5+4 then it goes up as it adds to then it is 9+5 then 14+6 then to 20+7 and so on. 5,9,14,20,27,35.
