if a scale drawing of a car is 3 inches and the real car is 15 feet what is the scale and scale factor

Step-by-step explanation:

Given parameters:

Scale drawing of the car  = 3 inches

Real car  = 15feet

Unknown:

Scale  = ?

Scale factor  = ?

Solution:

The scale is the ratio of the model dimension to the real-life representation.

 In this problem, express both quantities in the same unit;

          1 foot  = 12 inches

         15 feet  = 15  x 12  = 180inches

 Scale;

               drawing of the car : Real car

                      3 inches   :      180 inches

 Scale 1 inches on drawing is 60inches in real life

Scale factor;

                  =   = 60

The scale factor = 60

135 is your answer

step-by-step explanation:

try 180 times three then divide that number by 4 (sides) to get your answer. im glad to : )
