Dawis spent 5%2F6 of an hour total time traveling. 

                 speed    time    distance
TO GYM            6        ()      d
BACK HOME         4        ()      d
Total                     5%2F6

RT=D relates speed, time, distance for travel.
RT%281%2FR%29=D%281%2FR%29
T=D%2FR 
                 speed    time    distance
TO GYM            6        d%2F6      d
BACK HOME         4        d%2F4      d
Total                     5%2F6
