Joan wants to visit her family who live 480 miles away.  If she drives at a rate of 60 mph and takes a lunch break taking 30 minutes, and 2 bathroom breaks taking 15 minutes each, how many hours did it take her to get there?
The driving time is 480/60= <<480/60=8>>8 hours
The time for breaks was 30+15+15=<<30+15+15=60>>60 minutes
So she spent 60/60=<<60/60=1>>1 hour for rest stops.
So it took her 8+1=<<8+1=9>>9 hours
