Problem data: S (distance traveled by the body under consideration) = 16 km; t (time of body movement) = 4 hours.

SI system: S = 16 km = 16 * 10 ^ 3 m; t = 4 h = 4 * 3600 = 14 400 s.

1) Body speed in km / h: V = 16/4 = 4 km / h.

2) Body speed in m / s: V = 16 * 10 ^ 3/14400 = 1.11 m / s.

Answer: The speed of the body in question is 4 km / h or 1.11 m / s.
