a. How fast does the plane fly during the first leg of the trip?
b. How fast does the plane fly during the last leg of the trip?
c. What system of equations might be helpful in this scenario?
<u>s - speed of the plane, w - speed of the wind, equations:</u>
d. Solve this system of equations using the best method.

- 2s = 1100 ⇒ s = 550 mph
- w = 550 - 430 = 120 mph
e. How fast is the wind?
f. How fast does the plane fly without any wind?
