The key on a map shows 3/8th of an inch is 60 miles. if two cities are 4 5/8 inches apart, what is this value in miles?

740 miles

Step-by-step explanation:

You know that on the map is actually 60 miles and the distance between these two cities is .

You can express this distance as a decimal number:

Therefore, let be "d" the distance in miles between these two cities.

Then, you get:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
