Question 1
You travel 3 miles downstream in a kayak at a speed of r
miles per hour. You turn around and travel 4 miles upstream at a speed of 0.5r
miles per hour. Finally, you turn around and return to your original starting point at a speed of r+1

              SPEED          TIME          DISTANCE

GO               r           3/r              3

BACK           0.5r          4/(0.5r)         4

GO AGAIN       r+1           1/(r+1)          1

Total time in hours:
, which still could use simplification.
