Jack leaves at 2:15 pm to go to his mom's house. On the way, he stops twice for 45 minutes each time. He arrived at 4:30pm. If he drove 20 miles per hour the entire way, how far away does his mom live?

Okay to start, you want to figure out how long exactly he was driving. So you subtract 4:30-2:15 and that's equal to 2hrs 15mins or 135 minutes. Then it says he stopped for 45mins twice. [tex]45*2=90[/tex]
