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


__________________rate________time________distance
FRED______________r-5_________t___________36
SAMANTHA__________r___________t___________51

rate time distance.
if divide both sides by R.

Fred's time is the same as Samantha's time.

Solve for r. Compute r-5.
