A plane traveled k miles in its first 96 minutes of flight time. If it completed the remaining 300 miles of the trip in t minutes, what was its average speed, in miles per hour, for the entire trip?
$$A.\ \frac{60\left(k+300\right)}{\left(96+t\right)}$$
$$B.\ \frac{\left(kt+96\left(300\right)\right)}{96t}$$
$$C.\ \frac{\left(k+300\right)}{60\left(96+t\right)}$$
$$D.\ \frac{5k}{8}+\frac{60\left(300\right)}{t}$$
$$E.\ \frac{5k}{8}+5t$$
The OA is A
