Hi Skeeter! The wording of the the problem says to Determine the rocketâ€™s maximum height to three decimal places. (c.) Determine how long the rocket will spend in the air to three decimal places.

So unless I am doing something wrong again I am not ending up with Decimals

I got 20 seconds for the time in the air, and then 2460 feet for the Maximum height

Just because the directions say round solutions to three decimal places does not mean it will always be necessary to do so ... now, to find the time the projectile hits the ground will require the directions for rounding.
