Question

the scale model of the car is 1:18 the length of the model is 9 1/2 inches how many feet long is the actual
car

Answer 1

Answer:

14.25 ft

Step-by-step explanation:

1 inch of the model represents 18 inches of the real car. The car's dimensions are 18 times larger than the model's dimensions. Multiply the model dimension by 18 to find the corresponding real dimension.

9 1/2 * 18 = 9.5 * 18 = 171

The actual car is 171 inches long.

Now we need to convert 171 inches to ft.

1 ft = 12 in.

Since we want to eliminate inches and end up with feet, we divide both sides by 12 in.

(1 ft)/(12 in.) = 1

The conversion factor is (1 ft)/(12 in.) to go from inches to feet.

171 in. * (1 ft)/(12 in.) = 14.25 ft

Answer: 14.25 ft

Answer 2

Answer: The length of the car is 14 and 1/4 (or 14.25 ) feets long.

Step-by-step explanation:

The scale is 1:18.

The lenght of the car is 9 and 1/2 inches.

Then, for the ratio relation, we have that each inch in the model car we have that corresponds to 18 inches in the car, so the length of the car is:

L = (9 +1/2)*18 in = 9.5*18 in = 171 inches.

Now, remember that 1ft = 12 inches, so if we want to write this in feet we must divide this by 12.

L = (171/12) ft = 14.25 ft = (14 + 1/4) ft
