Flying against the wind, an airplane travels 8280 kilometers in 9 hours. Flying with the wind, the same plane travels 3900 kilometers in 3 hours. what is the rate of the plane in still and what is the rate of the wind?
rate of wind=?
rate of plane in still air=?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

the answer is about 24 dollars

answer is 17
