To determine the distance Kevin walked each minute, we can use the expression that represents dividing the total distance by the total time.
In this case, Kevin walked three-fourths of a mile in 12 minutes, so we can express the distance walked each minute as:
\[ \text{Distance walked each minute} = \frac{\text{Total distance}}{\text{Total time}} = \frac{3/4 \text{ mile}}{12 \text{ minutes}} \]
This means we need to divide three-fourths of a mile by 12 minutes, which corresponds to:
Three-fourths divided by 12
Therefore, the correct expression is:
Three-fourths divided by 12.
