You need to move from position B to position A as shown in the diagram above. Suppose W = 45 m and L = 184 m and you complete the trip in 62 s. The river flows at 1.6m/s in the direction shown.

1. How fast and in what direction must you paddle a boat to reach point A?
2. How fast must you paddle for the return trip along the same path to take the same amount of time?
