Huck Finn walks at a speed 0.70 m/s of across his raft (that is, he walks perpendicular to the raft’s motion relative to the shore). The heavy raft is traveling down the Mississippi River at a speed of 0.58 m/s relative to the river bank. What is Huck’s velocity (speed and direction) relative to the river bank?
