To compare the speeds of a hare and a dolphin, let’s translate the speed of a dolphin, equal to 18 km / h, into system units of speed measurement in m / s in accordance with the SI system:
18 km / h (1 km = 1000 m, 1 h = 3600 s) = 18 * 1000/3600 = 18000/3600 = 5 m / s.
Answer: Since 15 m / s> 5 m / s, the hare will move faster.
