Question 169023
    A jet-liner and a propeller driven aircraft leave two cities 3000km apart at the same time and fly toward each other on a collision course. The flights are non-stop. If the propeller driven plane flies at 300km/h and the jet at 600km/h, how far will the jet fly before these planes crash?
.
Applying the "distance formula".
.
Let t = time it takes to crash
.
300t + 600t = 3000
900t = 3000
t = 3000/900
t = 30/9
t = 3.33333 hours
or
3 hours 20 minutes
