Huck Finn walks at a speed of 0.60 m/s across his raft (that is, he walks perpendicular to the raft's motion relative to the shore). The raft is traveling down the Mississippi River at a speed of 1.75 m/s relative to the river bank. What is Huck's velocity (speed and direction) relative to the river bank?
