To find the actual distance the Patel family will travel, we first need to convert the distances on the map into actual miles using the provided scale: 12 inches equals 4 miles.
Step 1: Calculate the total distance on the map.
The distances on the map are:
- Smithville to Jonesville = 334 inches
- Jonesville to Clarksville = 514 inches
Total distance on the map = \( 334 + 514 = 848 \) inches.
Step 2: Calculate the actual distance based on the scale.
From the scale, we know: \[ 12 \text{ inches} = 4 \text{ miles} \]
To find out how many miles correspond to 1 inch, we can calculate: \[ 1 \text{ inch} = \frac{4 \text{ miles}}{12 \text{ inches}} = \frac{1}{3} \text{ miles per inch} \]
Step 3: Convert the total distance from inches to miles.
Now, we convert the total distance of 848 inches to miles: \[ \text{Actual distance} = 848 \text{ inches} \times \frac{1}{3} \text{ miles per inch} = \frac{848}{3} \text{ miles} \approx 282.67 \text{ miles} \]
The actual distance the Patel family will travel by the time they reach Clarksville is approximately 282.67 miles.
