Jon starts out on a trip at 50mph. If 20 minutes later, Joel starts out on the same route at 65mph, how long will it take Joel to overtake Jon? Round to the nearest hour.

Answer 1

Answer: 1 hour

`65t=(50)/(3) +50t`

Answer 2

20 minutes = ⅓ of an hour, so Jon was ⅓ hr × 50 mi/hr = 50/3 mi out before Joel starts.

Let t represent the time that Joel drove @ 65 mph

Joel traveled t hr × 65 mi/hr = 65t mi
Jon traveled 50/3 + 50t miles

So 65t = 50/3 + 50t must be equal
