The description is missing time for cycling the same distance.
                SPEED       TIME       DISTANCE
WALK            r            6          d
CYCLE           r+7          t          d

The question asks for r and r+7.

6r=t%28r%2B7%29
6r=tr%2B7t
6r-tr=7t
%286-t%29r=7t

highlight_green%28r=%287t%29%2F%286-t%29%29
