When looking for velocity, it's the first derivative of the
distance formula, so v = 17.16 T and then it says how long will
it take for it to reach 20.8?
So we're going to put 20.8 for the velocity, we're going to
divide each side by 17.16 and we get 1.21.
It asks us to round in the nearest 10th, so 1.2.
