To find the scale factor, we need to compare the lengths of the scale model to the actual car. We have the length of the scale model (3 inches) and the length of the actual car (16 feet). First, we need to convert the lengths to the same units. Let's convert the length of the car from feet to inches:
1 foot = 12 inches.
So, the length of the car in inches is:
16 feet * 12 inches/foot = 192 inches.
Now, we can find the scale factor by dividing the length of the actual car by the length of the scale model:
Scale factor ={192}/{3} = 64
The scale factor is 64, which means that one unit on the scale model represents 64 units in the actual car.
