Question 184878
<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r_s + r_w = 200]


and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ r_s - r_w = 120]


Because the wind adds to your speed when you are going with the wind and subtracts from your speed when you are going against it.


Solve the linear system for *[tex \Large r_s] and *[tex \Large r_w]
