Ted was assigned the task of watching the pool drain at the end of summer. He noticesaid the level has gone down 2 feet in 3/5 of an hour. Since it drains at a constant rate, how much water is drained per hour?

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)
