A Rube Goldberg machine consists of a series of devices that perform a simple task. Kate is drawing a scale model of her Rube Goldberg machine, which she plans to build and enter into a contest. A bicycle wheel on the scale model is 2 inches in diameter, while in the actual machine, it will be 28 inches in diameter.

Question 1
Part A

Based on the measures of the wheel diameter, what is the unit rate of inches of machine per inch of the model?

Answer:

The unit rate is 16

Step-by-step explanation:

The unit rate of the machine is given as 14 inches per model.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The diameter of bicycle wheel on the scale model is 2 inch.

And, the diameter in actual machine is 28 inch.

The unit rate of the machine can be found by using unitary method as follows,

For 2 inch diameter on scale model, diameter in machine = 28 inch

For 1 inch diameter on scale model, diameter in machine = 28/2 inch

                                                                                                = 14 inch.

Hence, the unit rate of inches of machine per inch of the model is 14 inches per model.
