John finds that the distance between two landmarks on a map is 6 1/2inches. If the map scale reads 3/4 inch=120 miles, what is the actual distance between the two landmarks?

I know that 6 inches would be 960 miles but im not sure how to calculate the last 1/2 inch. please help.

    I want to know why the knucklehead mapmapkers included a scale that reads "3/4 inch=120 miles" instead of one that read "1 inch = 160 miles" like any sane person would have done.2012-09-18

    I suspect that there's no such map - this smells like homework to me.2012-09-18
