A model is made of a car. The car is 10 feet long and the model is 6 inches long. What is the ratio (in inches) of the length of the car to the length of the model?
To find the ratio of the length of the car to the length of the model, we need to convert both lengths to the same unit of measurement.
Since the car's length is 10 feet and the model's length is 6 inches, we need to convert 10 feet to inches.
1 foot is equal to 12 inches, so 10 feet is equal to 10 x 12 = 120 inches.
Therefore, the ratio of the length of the car to the length of the model is 120 inches : 6 inches, which simplifies to 20:1.
So, the ratio of the length of the car to the length of the model is 20:1 in inches.
