A spacecraft with a volume of 800 cubic feet is leaking air at a rate of .4 cubic feet every n minutes. How many minutes until the spacecraft has no air?
800 cubic feet / .4 cubic feet every n minutes = 2000 (n minute parts)
Total time = 2000n
800 cubic feet / .4 cubic feet every n minutes = 2000 (n minute parts)
Total time = 2000n
