4.3 Systems of Linear Equations and Problem Solving

Question

An airplane takes 4 hours to travel a distance of 3200 miles with the wind. The return trip takes 5 hours against the wind. Find the speed of the plane in still air and the speed of the wind.

Answer 1

s represents the speed of the plane

w represents the speed of the wind

 

3200 = (s + w)4

3200 = (s - w)5

 

Can you solve the system and answer?
