A system of measurement; Based on Multiples of 1
A system of measurement for length, weight, time, and capicity used in the United States
A system of measurement for length, weight, time, and capicity not used by scientists across the world

The image shows a topographic map for three different wildlife preserves.
There are also six different profiles of hikes taken across the wildlife preserves. Each profile describes the change in elevation a hiker would experience if he or she hiked N - S across the wildlife preserve or E - W across the wildlife preserve.
Match each profile with the wildlife preserve hike it is describing.
hike profile C
hike profile F
hike profile D
hike profile B
hike profile A
hike profile E
