To compare speeds, they must be reduced to the same units of measurement.
8.3 m / s = 8.3 * 3.735 = 29.88 km / h.
Let’s compare 72 km / h and 29.88 km / h.
72 km / h> 29.88 km / h.
Method 2.
72 km / h = 72 / 3.6 = 20 m / s.
20 m / s> 8.3 m / s.
Answer: the speed of the dolphin is greater than the speed of the shark.
