the length of a car measures 20 feet. what is the length of a model car if the scale factor is 1:64 inches?

To find the length of the model car, we need to convert the scale factor to feet and then use it to calculate the length.

Scale factor: 1:64 inches
1 foot = 12 inches

To convert the scale factor to feet, we divide the inch measurement by 12:
64 inches / 12 = 5.33 feet

If the scale factor is 1:64 inches, it means that 1 unit on the model car corresponds to 64 inches in real life. Therefore, the length of the model car can be calculated by multiplying the length of the real car by the scale factor:

Length of model car = Length of real car * Scale factor
Length of model car = 20 feet * 5.33 feet
Length of model car = 106.6 feet

Therefore, the length of the model car is 106.6 feet.
