Answer 1

To determine the range of a data set, you subtract the smallest number from the largest number.

The numbers Ron biked are: 31, 35, 49, 32, 45, 29, 33, 28, and 40.

1. Find the maximum:
- The largest number is 49.

2. Find the minimum:
- The smallest number is 28.

3. Calculate the range:
\[
\text{Range} = \text{Maximum} - \text{Minimum} = 49 - 28 = 21 \text{ miles}
\]

Thus, the range of this data set is **21 miles**.
