One automobile starts out from a town at 8 a.m. and travels at an average speed rate of 60mph. 2 hours later, a second automobile starts out to overtake the first. If the second automobile travels at an average rate of 80mph, how long will it travel before it overtakes the first?

The distance betqeen the two autos is 2 x 60 = 120 miles

the closing rate is 80 m/hr - 60 m/hr = 20 m/hr

120 miles / 20 m/hr = 6 hours to catch first auto after second begins
