A boat is traveling upstream in the positive direction of the x axis at 12 km/h with respect to the water of a river. The water is flowing at 5 km/h with respect to the floor
(a) Find the velocity of the boat with respect to the floor?
km/h
(b) A kid on the boat walks from front to rear at 8 km/h with respect to the boat. Find the kid's velocity with respect to the floor?
