The speed of the shark is 8.3 m / s parents, and the speed of the dolphin is 72 km / h. Which of them has the highest speed?

The condition gives the speed of two sea animals – a dolphin and a shark, but they are given in different units.

Given:

V shark = 8.3 m / s (shark speed);

Dolphin V = 72 km / h (dolphin speed).

We need to find:

which of them has great speed?

We cannot compare the values given in different units of measurement, so we convert the speed of the dolphin from km / h to m / s:

72 km / h = (72 * 1000 m) / (1 * 3600 s) = 20 m / s.

So the speed of the dolphin is greater than the speed of the shark.

Answer: the dolphin has great speed.
