Suppose a person gets on a circular Ferris wheel at time t = 0 seconds at the minimum height of h = 4 meters above the ground and reaches a maximum height of h = 20 meters above the ground sometime later. One revolution around the Ferris wheel takes approximately 60 seconds. At what time(s) during the first revolution is the person at a height of 10 meters above the ground? An algebraic solution using an appropriately created model is required; no guessing or estimating is allowed. TYPE OR WRITE response/answer CLEARLY.
