A model car is 5 inches long. The actual length of the car is 15 feet . What is the scale factor of the model car?
Elodia [21]

Answer:

1 : 36

Step-by-step explanation:

To obtain the scale factor, the dimensions must be in the same units.

Using the conversion

1 foot = 12 inches, then

15 feet = 15 × 12 = 180 inches, thus

scale factor = 5 : 180 ← divide both parts by 5

scale factor = 1 : 36
