Final answer:
The total distance covered by a student running at a constant velocity of 4 m/s for 30 seconds is 120 meters.
Step-by-step explanation:
The student ran at a constant velocity of 4 m/s for a total of 30 seconds. To find the total distance covered, we can use the formula for distance when velocity is constant: distance = velocity × time. So, we multiply the velocity of 4 m/s by the time of 30 seconds.
distance = 4 m/s × 30 s = 120 m
Therefore, the total distance covered by the student is 120 meters.
