Question

Write and solve an equation to answer the question. A swimmer wins the 50-yard freestyle with a time of 24.76 seconds. Find the swimmer's average speed to the nearest hundredth of a yard per second. Use s for the variable.

Answer 1

To find the swimmer's average speed in yards per second, we can use the formula:

average speed = distance ÷ time

In this case, the distance is 50 yards and the time is 24.76 seconds.

Substituting these values into the formula:

average speed = 50 yards ÷ 24.76 seconds

Calculating this division, we find that the average speed is approximately 2.02 yards per second.

Therefore, the swimmer's average speed, to the nearest hundredth of a yard per second, is 2.02 yards per second.

Answer 2

The equation relating distance, time, and speed is: Speed = Distance / Time.

s = 50 yards / 24.76 seconds

≈ 2.02 yards/second.

So, the swimmer's average speed is approximately 2.02 yards per second.
