..., with current, as it does to travel TWO miles upstream , against current.
             SPEED      TIME           DISTANCE

UPSTR        29-c       2/(29-c)          2

DOWNSTR      29+c       3/(29+c)          3

2%2F%2829-c%29=3%2F%2829%2Bc%29
-
2%2829%2Bc%29=3%2829-c%29
2%2A29%2B2c=3%2A29-3c
0%2B2c=29-3c
5c=29
