A boat traveled 27 miles in 3 hours. At this rate, how many miles will the boat travel in ½ hour?

To find the distance the boat will travel in ½ hour, we first determine its speed by dividing the total distance of 27 miles by the time of 3 hours, resulting in a speed of 9 miles per hour. Next, we multiply this speed by 0.5 hours to find the distance traveled in that time frame. Therefore, the boat will travel 4.5 miles in ½ hour.
