Hi am having trouble solving this. I don't know how to set it up. Thanks for any help.
Kelly and Chris are shopping in the city. Chris leaves for home in his car at 3:00 traveling at 48 miles per hour, but Kelly is engrossed in a shoe store and doesn't leave until 3:15. If she drives at 66 miles per hour, how long after she leaves does she catch up with Chris?
