I'm really stuck! flying agents the wind, an airplane travels 7440km in 8 hours. flying with the wind, the same airplane travels 4840km in 4 hours. what is the rate of the plane in still air? what is the rate of the wind?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
