Final answer:
One inch on the map is equal to 1000 miles.
Step-by-step explanation:
To find what one inch would equal on the map, we can set up a proportion using the given information. We know that three-fourths of an inch on the map equals 750 miles. Therefore, the proportion would be: 3/4 inch = 750 miles. To find what one inch would equal, we can cross multiply and solve for the missing value:
3/4 inch * 1 inch = 750 miles * 1 inch
Simplifying, we get: 3/4 = 750 miles * 1 inch
Dividing both sides by 3/4, we get: 1 inch = (750 miles * 1 inch) / (3/4)
Simplifying further, we find that one inch on the map is equal to 1000 miles.
