Answer:
48 ft
Explanation:
Red balloon: r = 2 ft/s, d = x
Blue balloon: r = 3 ft/s, d = 60-40-x
d = r*t
Red balloon: d = x/2
Blue balloon: d = (20 - x)/3
x/2 = 20 - x)/3
3x = 2(20 - x)
3x = 40 - 2x
5x = 40
x = 8
Red balloon is 40 feet above the ground + 8 = 48 ft
Blue balloon: 60 - 40 = 20 - 8 = 12
60 - 12 = 48 ft
