Kevin walked Three-fourths of a mile in 12 minutes. Assuming he walked at a constant speed the entire time, which expression can be used to determine the distance he walked each minute?

Question

12 divided by three-fourths
12 times three-fourths
Three-fourths divided by 12
Four-thirds divided by 12

Answer 1

To determine the distance that Kevin walked each minute, you can calculate his speed, which is distance divided by time.

In this case, the distance he walked is $\frac{3}{4}$ mile, and the time taken is 12 minutes.

The expression to find the distance he walked each minute (which is the speed) is:

$$\text{Speed}=\frac{\text{Distance}}{\text{Time}}=\frac{\frac{3}{4}\text{ mile}}{12\text{ minutes}}$$

This can be simplified as:

$$\frac{3}{4}÷12$$

This is equivalent to the expression:

$$\frac{3}{4}÷12$$

Thus, the correct choice from the options is:

Three-fourths divided by 12.
