I can't tell exactly what you're asking, but my best guess is that you're looking for how many miles he bikes per hour. Brandom bikes 76 miles every hour.
Time =(distance)/speed
Time taken by the raft going with the current to travel x miles is:
12/x hours
Time taken by the raft going against the wind is:
7/y

12/x+7/y=4
hence the answer is:
<span>D. x/12 + y/7 = 4</span>
