Final answer:
The velocity of a student who walks 100 meters in 30 seconds is calculated as 3.33 m/s, by dividing the distance by the time.
Step-by-step explanation:
The velocity of a student who walks 100 meters in 30 seconds can be calculated by dividing the distance by the time. Since velocity is a measure of how fast an object is moving in a specific direction, it is a vector quantity and is usually expressed in meters per second (m/s). In this case, we divide 100 m by 30 s to get:
Velocity = Distance / Time = 100 m / 30 s = 3.33 m/s.
So, the student's velocity is 3.33 meters per second.
