The boast has to get there

A_________________________


W=45m – <——- Flow of the water


__-_______________________B

A boat is to travel from position B to position A in 62 seconds as identified on the diagram above. Let the river width W and horizontal length L be defined as follows:
W= 45 m and L = 184 m. The river flows at 1.6m/s to the left as shown in the diagram above.
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?
