Answer:
Senny: 45 mph; Farouk: 35 mph
Step-by-step explanation:
Their combined speed is 520 mi/(6.5 h) = 80 mi/h. Senny's speed is half the sum of this and the difference of 10 mi/h:
... (80 mi/h + 10 mi/h)/2 = 45 mi/h
Farouk's speed is 10 mi/h less:
... 45 mi/h - 10 mi/h = 35 mi/h

<em>Comment on Sum and Difference Problems</em>
If two numbers <em>a</em> and <em>b</em> have a sum of <em>s</em> and a difference of <em>d</em>, you can write equations ...
Adding these two equations gives ...
... 2a = s + d
Dividing this by 2 gives
... a = (s + d)/2 . . . . . . the formula we used above
