(II) Find the unit rate. The race car completed 12.8 miles in 4 minutes . Enter your answer. square miles per minute

## Step 1<br />The problem is asking us to find the unit rate, which is the rate of miles per minute. The unit rate is a way of comparing different rates by setting them equal to 1. In this case, we are given that the race car completed 12.8 miles in 4 minutes.<br /><br />## Step 2<br />To find the unit rate, we need to divide the total miles by the total minutes. This will give us the rate of miles per minute.<br /><br />### **Formula**: <br />The formula to calculate the unit rate is:<br /><br />\[<br />\text{Unit rate} = \frac{\text{Total Miles}}{\text{Total Minutes}}<br />\]<br /><br />## Step values into the formula:<br /><br />\[<br />\text{Unit rate} = \frac{12.8 \text{ miles}}{4 \text{ minutes}}<br />\]
