Answer:
2.9 minutes
Step-by-step explanation:
Given
[tex]Rate = 12 gallon/minute[/tex]
[tex]Size = 35\ gallon[/tex]
Required
Determine the time spent
The rate is a ratio of size to time
So, it can be expressed as:
[tex]Rate = \frac{Size}{Time}[/tex]
Substitute values for Rate and Size
[tex]12 = \frac{35}{Time}[/tex]
Cross Multiply
[tex]12 * Time = 35[/tex]
Solve for Time
[tex]Time = 35/12[/tex]
[tex]Time = 2.9[/tex] (approximated)
