A river flows with a velocity represented by vector A, where A= m/s, as shown in the figure. You steer a motorboat across the river; your velocity relative to the water is represented by vector B, where B= m/s, as shown in the figure. What is the speed of the motorboat relative to a person standing on the riverbank? Express your answer in m/s.
