A certain map shows two roads. Road A is 1 1/5 miles long but it is 1 4/5 long on the map. What is the unit rate for inches per mile? If road B is 4 miles long, how long is road B on the map?

6 inches

Step-by-step explanation:

Road in inches = 1 ⁴/₅

Road in miles = 1 ¹/₅

Inches per mile = 1 ⁴/₅ / 1 ¹/₅

= 1.5 inches

If the road is 4 miles long, on the map it would be;

= 1.5 * 4

= 6 inches

i think the correct option is the second option.
