The scale on a map is 1 inch represents 8 miles. If two cities are 2 1/2 inches apart on the map, how far are they in reality?(1 point) miles apart =
To solve this problem, we need to multiply the length on the map by the scale factor.
The length on the map is 2 1/2 inches. We can convert this to a fractional form by finding a common denominator: 2 1/2 = 5/2 inches.
The scale factor is 1 inch represents 8 miles. So, for every 1 inch on the map, there are 8 miles in reality.
To find the distance in reality, we multiply the length on the map (in inches) by the scale factor:
5/2 inches * 8 miles/1 inch = (5/2) * 8 miles = 40 miles.
Therefore, the two cities are 40 miles apart in reality.
