Question

Selma’s class is making care packages to give to victims of a natural disaster. Selma packs one box in 5 minutes and has already packaged 12 boxes.

Answer 1

I'm not sure what your asking, but if your asking how long it took her, it took her one hour. There is 12 boxes, and each one took her 5 minutes. 12*5 is equal to 60.
