Step 1 :Let the interval on the number line be represented by \((3.49,6.59)\).
Step 2 :To find the middle of the interval, calculate the average of the two endpoints. This can be done by adding the two endpoints and dividing by 2: \((3.49 + 6.59) / 2 = 5.04\).
Step 3 :To find the distance from the middle of the interval to either endpoint, subtract the middle value from one of the endpoints. The absolute value of this difference will give us the distance: \(|5.04 - 3.49| = 1.55\).
Step 4 :Final Answer: The value in the middle of the interval is \(\boxed{5.04}\) and the distance from the middle of the interval to either endpoint is \(\boxed{1.55}\).
