A private plane leaves an airport and flies due east at 192 miles per hour. Two hours later, a jet leaves the same airport and flies due east at 960 miles per hour. How long will the private plane fly until it is passed by the jet?

1. 960t - 192(2) = 192t
960t - 384 = 192t
-384 = 192t -960t
-384 = -768t
t = .5
.5 hour
1/2 hour
