Maps

Hello and good evening,

I need help with two math questions. The 1st is: On a map, the distance between 2 towns is 4 3/4 inches. The actual distance between the towns is 380 miles. What is the scale of the map. (How do I work this problem)
2nd question is: Charlene has eight more dollars than Dre. Together they have $86.00. Write an equation that can be used to determine the amount of money,m,Dre has. I got this (8+m)+m=86 I need to knoe if I am on the right track. Thanks in advance!

Hello, Mysunz,

For the map problem, there is more than one way to state the scale. Probably all they want to know is what 1” is equivalent to. To state the answer in these terms, just divide the number of miles by the number of inches:

380/4.75 = 80

This means that 1" on the map is equivalent to 80 miles.

You have approached the second problem correctly. Just solve for m now.
