SUMMARY
The resultant velocity of a long-distance swimmer swimming at 2 mph at 30 degrees south of west, while encountering a 5 mph current flowing at 10 degrees north of east, can be calculated using vector components. By breaking the velocities into their respective x and y components and summing them, the swimmer's resultant velocity can be determined. The formula used is v r-hat = v cos @ x-hat + v sin @ y-hat, which allows for the recombination of the components to find the final velocity vector.
