Two hot air balloons are flying above a park. one balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate of 40 feet per minute. the second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground. given that his the height of the balloons after m minutes, determine which system of equations represents this situation. a. h = 3,000 + 40m h = 1,200 - 50m b. h = 3,000m - 40 h = 1,200m + 50 c. h = 3,000 - 40m h = 1,200 + 50m d. m = 3,000 - 40h m = 1,200 + 50h
