__________________rate__________time___________distance
FIRST_____________r+5__________(____)___________75
SECND_____________r____________(____)_________(_____)
Total__________________________________________100


Some elements are missing from the data table above.
Knowing that the sum of distances must be 100, and the two-times time relationship, the missing elements can be filled.


__________________rate__________time___________distance
FIRST_____________r+5__________%2875%2F%28r%2B5%29%29___________75
SECND_____________r____________(25%2Fr)_________(25)
Total__________________________________________100

the faster cyclist rode for twice the amount of time as the slower one,
highlight_green%2875%2F%28r%2B5%29=2%2825%2Fr%29%29.
