Question

Erin finds that an actual distance of 145 miles in her city is equivalent to 38 of an inch on a map. The map includes a legend that lists the number of miles represented by 1 inch. How many miles per inch are listed in the legend?

Answer 1

3.82 miles per inch are listed in the legend.

Explanation:

Given that:

Actual distance = 145 miles

Distance on map = 38 inches

38 inches = 145 miles

We have to find the number of miles represented by 1 inch.

1 inch on legend =
`(Actual\ distance)/(Distance\ on\ map)`

1 inch on legend =
`(145)/(38)`

1 inch on legend = 3.82 miles

Hence,

3.82 miles per inch are listed in the legend.
