A pool drains water at a rate of 3% every 5 minutes how many gallons of water are left after 50 minutes? How long will it take to have less then 1,000 gallons?

Answer 1

5 minutes depletes 3% of water
1 minute depletes 3/5 % of water
50 minutes depletes (3/5)(50) % or 30% of water

We can't answer the number of gallons, unless we know how many gallons we started with
