Question

According to the key of a particular park map, every 8 inches on the map represents 3 miles of trails in the park. How many inches on the map represents 9 miles on the park trails

Answer 1

24 inches represents 9 miles in the map

Explanation:

To solve this problem you take into account that 8 inches represents 3 miles and that x represent the number of inches for 9 miles. That is:

8 ------- 3

x ------- 9

This is simply a rule of three, then you calculate:

`x=(8\ x\ 9)/(3)=(72)/(3)=24`

Hence, 24 inches represents 9 miles in the map
