Question 484518
<font face="Times New Roman" size="+2">


Distance equals rate times time, or better for our purposes, rate equals distance divided by time.


So the rate of the aircraft MINUS the wind speed is equal to 750 miles divided by 2.5 hours.


The rate of the aircraft PLUS the wind speed is equal to 750 miles divided by 2 hours.


So


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ -\ r_w\ =\ 300]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r\ +\ r_w\ =\ 375]


Solve the system for *[tex \Large r] and *[tex \Large r_w].  Hint: Use the Elimination Method.
