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.Given information:- Distance traveled: 250 m- Time taken: 308 secondsAverage speed = Total distance / Total timeAverage speed = 250 m / 308 sAverage speed ≈ 0.813 m/sTherefore, the student's average speed is approximately 0.813 meters per second.
