A 20 gallon fish tank is being filled at a rate of 2 gallons per minute.At this rate,how many minutes will it take to fill this
2 answers:
Since 3/4 of 20 is 15, 15 is 3/4 of tank.
Then since the tanked is being filled at a unit rate of 2 I would do 2 * 7.5 which is 15 :D Yay!
Then I would do 1 * 7.5 which is 7.5
So, the tanked would be filled at 3/4 in 7.5 minutes or 7 1/2 a minute.
The answer is 7 and a half
