1. A student practicing for a cross country meet runs 250 m in 308. What is her average speed?

To calculate the average speed, we need to divide the total distance traveled by the total time taken.<br /><br />Given information:<br />- Distance traveled: 250 m<br />- Time taken: 308 seconds<br /><br />Average speed = Total distance / Total time<br />Average speed = 250 m / 308 s<br />Average speed ≈ 0.813 m/s<br /><br />Therefore, the student's average speed is approximately 0.813 meters per second.
