Each of them need to work 105 minutes more in order to have packed the same number of boxes.

Explanation

Suppose, they need to work for minutes more in order to have packed the same number of boxes.

Selma packs one box in 5 minutes and Trudy packs one box in 7 minutes.

So, the number of boxes packed by Selma in that minutes and the number of boxes packed by Trudy in minutes

Given that, Selma and Trudy have already packed 12 and 18 boxes.

Now if each of them packed the same number of boxes, then the equation will be......

So, each of them need to work 105 minutes more in order to have packed the same number of boxes.
