"In the time it takes...", some time t.


__________________rate________time________distance
FRED______________r-5_________t___________36
SAMANTHA__________r___________t___________51

RT=D rate time distance.
T=D%2FR if divide both sides by R.

Fred's time is the same as Samantha's time.
highlight_green%2836%2F%28r-5%29=51%2Fr%29
Solve for r. Compute r-5.
