If an object that is 85 ft long is represented on a scale drawing as a line 5 in. long, what is the scale used to make the drawing?

85 ft = 85 * 12 = 1020 inches

So the scale to the real is :

5 : 1020 (simplify)

1 : 204

Thank you for answering! That's what I came up with also but the choices include -->

(1) 1 in. to 17 ft.

(2) 5 in. to 85 ft.

(3) 2 in. to 35 ft.

(4) 3 in. to 51 ft.

I'm a little confused.
