Although cheetahs are well known as the fastest sprinting animal on Earth, the lesser known pronghorn $($also known as the American antelope$)$ is the fastest long$-$distance running animal. Suppose you find a herd in the wild and measure how far they travel over a certain amount of time. Assuming they only travel in a straight line, if you measure that they travel $22\mathrm{.}13$ km in $15$ minutes, what is their $1)$ average speed and $2)$ average velocity? $$$$
