Problem 1

Here is a map of Yellowstone National Park. Use the map to answer the questions.

Map of Yellowstone National Park.

  1. About how long is the south border of the actual park?
  2. Estimate the actual area of the park. Explain your reasoning.
  3. A different map of Yellowstone National Park uses the scale 1 inch to 4 miles. How long is the south border of the park on that map?

Solution
  1. about 50 mi
  2. about 3,000 sq mi. Sample reasoning: The park is roughly a rectangle. The height of the park is about 60 mi and the width is about 50 mi. 50⋅60=3,00050 \boldcdot 60 = 3,000
  3. Sample response: 12.5 inches (if 50 mi is used as the actual length)
    Note: The answer here should be 14\frac14 of whatever value students have for the actual length of the south border of the park.
