<PRE><B>Question 114892</B>
seeing as the distances are all the same you have three legs whose additive times equal 50 min.
d=rt or:
t=d/r
d/12+d/16+d/16=5/6 find a common denominator for the left hand side of this equation. 
48 looks like a good choice.
(4d+3d+3d)/48=5/6 
10d/48=5/6 cross multiply
60d=5*48
60d=240
d=240/60
d=4 k for the distance of each leg.
proof
4/12+4/16+4/16=5/6
(4*4+3*4+3*4)/48=5/6
(16+12+12)/48=5/6
40/48=5/6
5/6=5/6
