Hyun Woo is riding a ferris wheel. $H(t)$ models his height (in $\text{m}$) above the ground, $t$ seconds after the ride starts. Here, $t$ is entered in radians.
>$H(t) = -10\cos\left(\dfrac{2\pi}{150}t\right) + 10$
**When does Hyun Woo first reach a height of $16\text{ m}$?**
*Round your final answer to the nearest whole second.*
