a)
From the information given, the ferris wheel makes a complete rotation in 16 minutes.
A complete rotation is 360 degrees. This means that each angle is
360/12 = 30 degrees
Lets us assume that the starting point is A. As the ferris wheel move towards the highest point at D, the angle covered is 30 + 30 + 30 = 90 degrees
We have the following equations
360 = 16
90 = (90 x 16)/360 = 4
b) Recall, 1 minute = 60 seconds
Thus, 16 minutes = 16 x 60 = 960 seconds
