Jacob is 14 years old. matthew is 10 years old. they work 120 minutes altogether. how many minutes does each boy work?

Divide 120 by 2. Given that there are only two people. Split it equally among the 2

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
