Question

a 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.
what is the difference, in feet, between the minimum and maximum heights of a car on the ferris wheel?
a. 0
b. 3.5

Explanation:

Step1: Identify maximum and minimum heights

From the graph, the maximum height is \(140\) feet and the minimum height is \(10\) feet.

Step2: Calculate the difference

The difference \(d\) is \(d = 140 - 10\).

Answer:

\(130\) (Since the options provided in the original problem might be incorrect as per the graph analysis. If we assume the graph - reading was wrong in the problem's options setup and follow the correct calculation from the described process of subtracting min from max height on a height - vs - time graph for a Ferris - wheel (a common problem in the'statistics' sub - field of Mathematics where data from a graph is analyzed)).
