What is the velocity of the water?
Also, is the swimmer at 45 deg such that they are swimming against the current or with the current?
A swimmer sets off from one bank. The velocity of the swimmer relative to the water is 1.2 m / s
at 45° to the river banks, as shown in Fig. 1.1.
In the space below, draw a scale diagram to determine the resultant velocity of the swimmer
relative to the river banks. This velocity is the resultant of the two velocities shown on Fig. 1.1.
Label this resultant on your diagram.

If the swimmer is swimming directly across the water stream, and his velocity is at a 45 degree angle, then the stream has to be equal to his veloicty relative to the water.
stream velocity (relative to ground) :1.2
his velocity (relative to stream):1.2
his velocity relative to ground=his velocity relative to stream + stream velocity relativ to ground.
This is true whether or not the direction of the stream, in the end, if he is swimming directly across, he is washed downstream at a 45 degree angle (relative to shore)
stream velocity (relative to ground) :1.2
