A hot-air balloon is being filled with air. After 20 minutes, the volume of the balloon is 75 cubic feet. After 60 minutes, its volume is 120 cubic feet. It takes 3 hours to fill the balloon at this constant rate, and the balloon was not empty initially. How much hot air does the balloon hold, and how much hot air was in the balloon initially?

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)
