A river flows with a velocity represented by vector A, where A= [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= [B] m/s, as shown in the figure. The river is 600 m wide in the x-direction. How much time is required to cross the river (in seconds, s)?

Points A and B are two boat landings located on the same bank of a river (in the x-direction). d= 5.0×103 m. The river flows with a velocity represented by vector C, where C= [C] m/s, as shown in the figure. A motorboat makes the round trip between the two landings in [t] s. What is the speed of the boat relative to the water (in m/s)?
