Answer:
13.5 minutes (13 minutes and 30 seconds)
Explanation:
In this problem, you are given the rate of which the water drips at which can be used to find the time of any amount of water that has dripped if using a ratio.
Drip rate: 3 min / 1 cup
If we set up a ratio, we can use X for the time it takes to waste 4 1/2 cups of water:
3 min / 1 cup = X min / 4 1/2 cups
Then, cross multiply to solve:
1*X=3*4 1/2
Simplify for the answer:
X= 13 1/2 minutes
(13 minutes and 30 seconds)
