Brian started cleaning at 3:33 PM and finished at 4:21 PM. The correct answer is 48 minutes

First, we are figuring out what is given we are counting numbers or we can add to get to 4:21 PM.

Counting numbers:

$\boxed{3:33=3:34=3:35=3:36=3:37=3:38=3:39=3:40 }$

Add the numbers:

$\boxed{3:33+7=3:40+10=3:50+10=4:00+21=4:21}$

If we add the numbers it would be faster.

Therefore, when we add we get are answer.

Therefore, Brian started cleaning at 3:33 PM and finished at 4:21 PM. The correct answer is 48 minutes
