the speed of an animal is how fast it is moving. a speed of 6 m/s (meters per second) means that the animal moves a distance of 6 meters every second.

1. how would you measure the speed of an animal?

1. what do you think are the fastest animals?

Explanation:

1. To measure the speed of an animal, you can measure the distance it travels over a specific period of time. Then use the formula \(speed=\frac{distance}{time}\).
2. Some of the fastest animals are cheetahs (on land), sailfish (in water), and peregrine falcons (in air).

Answer:

1. Measure the distance the animal travels and the time it takes, then use \(speed = \frac{distance}{time}\).
2. Cheetahs (land), sailfish (water), peregrine falcons (air).
