Final answer:
The actual distance between the Petrified National Forest and Meteor Crater is approximately 56.25 miles.
Step-by-step explanation:
To find the actual distance between the two sites, we first need to determine the scale of the map. The scale of the map states that 2 inches on the map represents 75 miles. Since the two areas are about 1½ inches apart on the map, we can calculate the actual distance as follows:
1.5 inches on the map represents (1.5/2) * 75 = 56.25 miles.
Therefore, the actual distance between the Petrified National Forest and Meteor Crater is approximately 56.25 miles.
