Suppose a hot air balloon begins descending at a rate of 30ft/min from an elevation of 1250ft. Write an equation to model the hot air balloon's elevation as a function of time.
base elevation is 1250 ft rate is 30 per minute 30m so, h = 1250 - 30m as an inclusion, 30 ft per minute is also like 0.5 per second like 1250 - 0.5s 1250/30 means it would be about 42 minutes once it touches the ground.
