What is the unitary method?
The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
In the given question Ferris wheel in Chicago goes around one time during each 7-minute ride.
The graph shows the height of a car on the Ferris wheel above the ground during a ride.
We need to find the difference, in feet, between the minimum and maximum heights of a car on the Ferris wheel.
The maximum heights of a car on the Ferris wheel is 150.
The minimum heights of a car on the Ferris wheel is 10.
So, we can calculate it as;
maximum heights - minimum heights
= 150 - 10
= 140
Therefore, the difference, in feet, between the minimum and maximum heights of a car on the Ferris wheel is 140. thus the correct option is C.
