Write as a unit rate. Travel 338 miles in 6.5 hours Select the correct choice below and fill in the answer box to complete your choice. (Simplify your answer.) A. \( \square \) hour(s)/mile B. \( \square \) hour(s) C. \( \square \) mile(s) D. \( \square \) mile(s)/hour

To find the unit rate for traveling 338 miles in 6.5 hours, we need to calculate the rate in miles per hour. We can do this by dividing the total miles by the total hours: \[ \text{Rate} = \frac{\text{Total Miles}}{\text{Total Hours}} = \frac{338 \text{ miles}}{6.5 \text{ hours}} \] Now, performing the division: \[ \frac{338}{6.5} = 52 \] So, the unit rate is 52 miles per hour. Now, we can fill in the answer box for the correct choice: D. \( 52 \) mile(s)/hour
