you fill up 40 gallon pool putting in 2 gallons water every minute, if someone scoops out 1 gallon every 8 minutes, how long would it take to fill the pool?
Answers
There's a catch here, and I don't really want to go into full detail. Because of this catch, I think it would be unusually tough to write a simple equation for this situation. If you wouldn't mind, let's just list it instead:
After . . water added . . total in pool
7 min . . . 14 gallons . . . 14 gallons 1 more . . 1 gallon . . . . . 15 gallons 7 more . . 14 gallons . . . 29 gallons 1 more . . 1 gallon . . . . . 30 gallons 5 more . . 10 gallons . . . 40 gallons, the pool is full
Add up all the minutes: 21 minutes
It would take 21 minutes As the first 8 minutes there would be 15 gallons in the pool In 16 minutes there would be 30 gallons in the pool Therefore you only need 10 gallons left which will be filled up in the space of 5 minutes
