Final answer:
The velocity of Horse's 1 is 20 m/s. Velocity is the main indicator of the position as well as the flow of the object. It can be measured from the distance covered by an object in unit time. Velocity can also be measured as the displacement of the object in unit time.
Step-by-step explanation:
To find the velocity of Horse's 1, we can use the formula:
velocity = distance/time
Given that Horse's 1 can gallop 20 meters in a second, means d = 20m, t = 1s
We can calculate the velocity as:
Velocity = 20 meters / 1 second = 20 m/s
Therefore, the velocity of Horse's 1 is 20 m/s.
