It takes a plane 3.5 hours to fly 2,345 miles and 2 hours to fly 860 miles going the opposite direction along the same route. I really just need help with c and d.

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?
d. Solve this system of equations using the best method.
e. How fast is the wind?
f. How fast does the plane fly without any wind?

See below

Step-by-step explanation:

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?

s - speed of the plane, w - speed of the wind, equations:

d. Solve this system of equations using the best method.

Add the equation together to get:

e. How fast is the wind?

f. How fast does the plane fly without any wind?

you never say the total so we cant find the percentage used for petrol
