If 84 people hiked around the smallest lake, about how many miles would they travel?

To determine the distance traveled by 84 people hiking around the smallest lake, we need to know the circumference (or perimeter) of the lake, which is the distance they would collectively cover.

If we assume that "the smallest lake" has an average circumference, and let's say for instance it's approximately 1 mile around the lake (this number can vary widely based on actual geographic data), then:

- Each person travels 1 mile.
- Therefore, 84 people would collectively hike \( 84 \times 1 = 84 \) miles.

If you have a specific circumference for the lake, you can substitute that into the calculation:

- For example, if the circumference is 0.5 miles, then \( 84 \times 0.5 = 42 \) miles.
- If it's 2 miles, then \( 84 \times 2 = 168 \) miles.

Please provide the circumference of the lake for a precise calculation or adjust the assumption as appropriate.
