Adelle sat down to dinner at 6:05 P.M. She took 55 minutes to do her homework, 25 minutes to walk her dog, and 15 minutes to ride her bike home after school. What time did she leave school?
Add up all the activity times listed: 55 +25+15 = 95 minutes. This is how much time has elapsed since Adelle left school. So count back 95 minutes from 6:05. You get 4:30.
