Aplane can travel 420 miles when it flies in the direction of the jet steam in the same amount of time it takes the plane to cover 160 miles when it is flying against against the jet stream. if the current of the jet stream is 5mph, at what rate was the plane traveling?

(-1,-0.5)

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

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
