Problem:Water flows from a bathroom tap at a rate of 2 gallons every 6 seconds. Questions At this rate, how many minutes will it take to fill an 80 - gallon tub?

4 minutes.

Explanation:

The rate of flow from the tap is 2 gallons every six second

which comes out to be 1 gallons per 3 seconds.

so for 80 gallons we can simply

3 * 80 = 240 which is 240 seconds.

Thus it would take 4 minutes to fill up the 80 gallon tub.
