On each hike, you saw a different number of animals: Hike Length of hike (\text{km})(km)left parenthesis, start text, k, m, end text, right parenthesis Number of animals seen Rivers Edge 333 888 Wooded Marsh 888 202020 Canyon Creek 151515 353535 Order your hikes by number of animals seen per kilometer from least to greatest.

Answer 1

Canyon Creek<Wooded Marsh<Rivers Edge

Explanation:

When hike length was 3 km and there are 8 animals, the number of animals seen per kilometer will be (8/3) = 2.67 animals/km

When hike length was 8 km and there are 20 animals, the number of animals seen per kilometer will be (20/8) = 2.5 animals/km

When hike length was 15 km and there are 35 animals, the number of animals seen per kilometer will be (35/15) = 2.34 animals/km

Canyon Creek<Wooded Marsh<Rivers Edge is the required order.
