Time Both way(Walking distance D+ Racing distance  D)   =9 hours 50 minutes = 9+50/60=59/6 ----i

Time Both way ( Walking distance 2 D) =12 hours 20 minutes =12+20/60=37/3

2 D=37/3  (Time walking both distances)

D=37/6 (Time walking distance D)

Walking distance D = 59/6  -37/6 =22/6

Walking distance  2D = 23/6*2 =22/3 = 7 hours 20 Minutes
