A. $1589.01
I solved this by a simple trial and error by inputing each answer into the equation.
Given that
, we have
, so that

Take the derivative and find the critical points of
:

Take the second derivative and evaluate it at the critical point:

Since
is positive for all
, the critical point is a minimum.
At the critical point, we get the minimum value
.
We have the function d, representing the distance from the ground of a person riding on a Ferris wheel:

If we consider the position of the person at t = 0, which is:

This position, for t = 0, will be the same position as when the argument of the sine function is equal to 2π, which is equivalent to one cycle of the wheel. Then, we can find the value of t:

Then, the wheel will repeat its position after t = 60 seconds.
Answer: 60 seconds.
