Answer:
8.33 meters per second
Step-by-step explanation:
The average speed of the student can be calculated by dividing the total distance she ran by the time taken:
Average speed = Total distance / Time takenIn this case, the total distance is 250 meters and the time taken is 30 seconds, so:
Average speed = 250 m / 30 sSimplifying the expression on the right-hand side:
Average speed = 8.33 m/sTherefore, the average speed of the student is 8.33 meters per second.
