Question 909097: A plane can fly 720 miles in the same time as it takes a car to go 200 miles. If the car travels 130 mph slower than the plane, find the speed of the plane Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! A plane can fly 720 miles in the same time as it takes a car to go 200 miles. If the car travels 130 mph slower than the plane, find the speed of the plane.
-------
Plane rate = 720/t mph
Car rate = 200/t mph
------
Equation::
plane rate - car rate = 120 mph
------
720/t - 200/t = 120 mph
----
720 - 200 = 120t
---
120t = 500
t = 4.16666...
---------------
Ans: plane speed = 720/4.16666 = 172.8 mph
---------------
