Great question! Similarly to the graph drawn in the explanation, the distance covered is the area of the triangle. We know the height of the triangle is $$ \frac{60 \times 5280}{3600} $$ and the length is 2.2. But the formula for a triangle requires that we divide by 2, so by multiplying what is above by 2.2, and then dividing by 2, we get the answer: $$ \frac{60 \times 5280 \times 2.2}{3600 \times 2} $$ For a more detailed intuition for why the 2 is on the bottom, a bit more physics is needed, but for now, I think the triangle explanation is a really good one!
