<task> <p> Suppose that <m>g(t)</m> gives the velocity in fps at time <m>t</m> (in seconds) of a particle moving in the vertical direction. A positive velocity indicates that the particle is moving up, a negative velocity indicates that the particle is moving down.

At what time does the particle reach the highest point in this time interval?</p></task>

You can have something like

<task>
   Task goes here
</task>

And PreTeXt helps you out and makes everything into the statement of the task. However, you cannot also have a <hint> or an <answer> when you do that. You must use a <statement> if you want to show an <answer>.
