Question 200381: a plane is descending at the rate of 640 feet per minute. now(at time zero), its altitude is 30,000 feet. negatgive times in the table mean minutes just past. positive times mean minutes to come. Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! a plane is descending at the rate of 640 feet per minute. now(at time zero), its altitude is 30,000 feet. negatgive times in the table mean minutes just past. positive times mean minutes to come.
-----------------
You didn't say what you want to do, but I'll give a formula for altitude as a function of time.
------------
A = 30000 - 640t (altitude in feet, t in minutes)
