Question

Whitney was visiting Big Bend Ranch

State Park. At the entrance, she saw a
map of the park. The legend stated
that 1.5 inches on the map represents
20 feet in the park. On the map, how
many inches would represent 60
actual feet?

Answer 1

4.5 inches on the map would represent 60 actual feet.

Explanation:

Given that:

1.5 inches on map represents 20 feet in the park.

x be the inches on map that represents 60 feet in the park.

Ratio of distance on map to actual distance :: Ratio of distance on map to actual distance

1.5 : 20 :: x : 60

Product of mean = Product of extreme

20*x = 1.5*60

20x = 90

Dividing both sides by 20

`(20x)/(20)=(90)/(20)\\x=4.5`

Hence,

4.5 inches on the map would represent 60 actual feet.
