Answer:
.2 Gallons a minute
.2G/1m
25minutes until empty
Explanation:
so the container lost 3 gallons in 15 minutes after that you changed it to how many minutes it took to lose 1 gallon by doing 15/3= 5
Now that you know 5/1 you divid 1/5 for an answer of 1/5 or .2 gallons a minute.
now you know that part two is easy
5/.2=25 which is the amount of times .2 gallon has to be removed from five and happens to also be the amount of minutes due to your solve from earlier.
