Answer: It took him 30 minutes to clean 12 pairs of shoes.


2 1/2 can be written as a decimal, 2.5, to make the equation simpler. It takes him 2.5 minutes per pair of shoes.

Given 12 pairs, we can find how long it took him using multiplication: 2.5(12) = 30
It took the Boy Scout 30 minutes to complete the task. This is also equivalent to half an hour.
