Step-by-step explanation:
Distance upstream = (34-c)(39/60) miles
--------------------------
Distance downstream = (34+c)(29/60) miles
-----------------------------------------------
Equation:
distance = rate*time
distance up = distance down
(34-c)(39/60) = (34+c)(29/60)
Multiply both sides by 60 to get:
39(34-c) = 29(34+c)
39*34 - 39c = 29*34 + 29c
68c = 340
c = 5 mph speed of the current
