Answer:
Part (A) The scale of 1 inch : 80 miles represents for each inch Keith needs to travel 80 miles.
Part (B) the distance between the two cities is 400 miles.
Step-by-step explanation:
Consider the provided information.
Part (A)
It is given that He measured a distance of 5 inches between the two cities on the national map in his road atlas. A scale of 1 inch:80 miles is displayed on this map
The scale of 1 inch : 80 miles represents for each inch Keith needs to travel 80 miles.
Part (B) Now we need to calculate the distance between Los Angeles and San Francisco.
The distance is 5 inches between the two cities on the national map in his road atlas.
The scale factor is given as: 1 inch:80 miles
Multiply both the sides by 5.
1×5 inch:80×5 miles
5 inch:400 miles
Hence, the distance between the two cities is 400 miles.
