Usain Bolt's average speed in yards per second was 11.4

Explanation:

1. Let's review the information given to us to answer the question correctly:

World record of Usain Bolt = 9.589 seconds

Distance of the world record = 100 meters

1 yard = 0.9144 meters ⇒ 100 meters = 109.36 yards

2. What was Usain Bolt's average speed in yards per second?

Let's recall that the formula of speed is:

Speed = Distance/Time

Replacing with the values we know:

Usain Bolt's Speed = 109.36/9.589

Usain Bolt's Speed = 11.4 yards per second (Rounding to one decimal place)
