Question 1079524: Jamie rides a Ferris wheel for five minutes. The diameter of the wheel is 10 meters,
and its center is 6 meters above the ground. Each revolution of the wheel takes 30 seconds.
Being more than 9 meters above the ground enables Jamie to see the ocean. For how many
seconds does Jamie see the ocean?

We want to know the fraction of the wheel's edge that is more than 9 meters above the ground.
The small arc between points P and Q represents the part of the ride when Jamie sees the ocean.
, and is the radius of the wheel.
So, in right triangle BAP,
---> (approximately
The fraction of each revolution that Jamie is between P and Q is
.
, so the time that Jamie sees the ocean is
