## Step 1<br />The problem provides a scale for a map, which is 1 inch represents 10 miles. This means that for every inch on the map, it represents 10 miles in real life.<br /><br />## Step 2<br />The problem also provides the distance between two cities on the map, which is 3.5 inches.<br /><br />## Step 3<br />To find the actual distance, we need to multiply the distance on the map by the scale of the map.<br /><br />### **Formula**: <br />The formula to calculate the actual distance is:<br />\[<br />\text{Actual Distance} = \text{Map Distance} \times \text{Scale}<br />\]<br /><br />## Step 4<br />Substitute the into the formula:<br />\[<br />\text{Actual Distance} = 3.5 \, \text{inches} \times 10 \, \text{miles/inch}<br />\]<br /><br />## Step 5<br />Calculate the actual distance:<br />\[<br />\text{Actual Distance} = 35 \, \text{miles}<br />\]
