Question

Harry is building a model car. The actual car has a length of 15 feet and tires with a radius of 24 inches. His model car has a length of 1.25 feet. In order to create an accurate model, the radius of the tires on his model car should be

Answer 1

  The answer would be 2 inches.
 The ratio of the model to the real figure is 1 feet to 12 feet, since 15 divided by 1.25 is 12. And since 24 inches = 2 feet, 2 divided by 12 would equal 1/6 feet, which would equals 2 inches.
