a sprinter runs 222yds in 25.2s find her average speed in yds/s
This really is an elementary question.
distance=avgvelocity*time
solve for avgvelocity
8.81 yds
To find the average speed of the sprinter in yards per second, you need to divide the distance covered by the time taken. In this case, the distance covered is 222 yards, and the time taken is 25.2 seconds.
To calculate the average speed, you can use the formula:
Average speed = Distance / Time
Plugging in the values, we have:
Average speed = 222 yards / 25.2 seconds
To simplify the calculation, divide 222 by 25.2:
Average speed ≈ 8.81 yards per second
Therefore, the average speed of the sprinter is approximately 8.81 yards per second.
