Question 5
Donovan leaves school to walk home. His friend, Pavati, notices 0.3 hours later that Donovan forgot his
phone at the school. So Pavati rides her bike to catch up to Donovan and give him the phone. If Donovan
walks at 2.2 mph and Pavati rides her bike at 9.6 mph, find how long (in hours) she will have to ride her
bike until she catches up to him.
