Asked by Anna

Lee built a scale model of his car. The model was
3 inches long. The scale from the model to Lee’s
car was 1 to 60. What was the length of Lee’s car?
A 20 inches
B 57 inches
C 63 inches
D 180 inches

I don't get it please help

3 inches : x inches = 1 : 60
x = 180 inches
= 15 ft
Ms. Sue
The scale is one inch on the model equals 60 inches on the real thing.

If the model is 3 inches long, then multiply 3 * 60 to find the length of the real thing.

But that is not one of the answer choises
Ms. Sue
Yes, it is.
Reiny
Well, it should be either 180 inches or 15 ft.
Anna
Ok so it is D (180 inches) ?
Anna
Ok is not 15 because 3 * 60 is 180 not 15 right?
Reiny
NO,
because 15 ft equals180 inches.

I do it this way: The scale is given 1/60. So, make a proportion, 1" is to 3" as 60" is to X OR 1/60 = 3"/X; therefore, X = 180". If you want it in feet then 180"/12" because [12 inches = 1 foot]. Thus...180 inches/12 inches = 15 feet.
