Plane B is flying 95 mph faster than Plane A. Find the time it takes for Plane A to travel 1425 miles
if it takes Plane B the same amount of time to travel 1710 miles.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let "u" be the speed of the plane A, in mph.
Then the speed of the plane B is (u+95) mph, according to the condition.
Flight time for plane A is hours ( remember, speed = distance/time ! )
Flight time for plane B is .
The condition says these times are the same (!). It gives you an equation
= .
You need to solve it for u.
To make it, multiply both sides by u*(u+95). You will get
1425(u+95) = 1710u.
