Question

In 2009, a Jamaican sprinter Usain Bolt created a world record in Berlin by running 100 m in just 9.58 seconds. What is his average speed?​

Answer 1

To find Usain Bolt's average speed, you can use the formula for average speed:

Average Speed = Distance / Time

In this case, the distance is 100 meters, and the time is 9.58 seconds. Plug these values into the formula:

Average Speed = 100 meters / 9.58 seconds

Now, calculate the average speed:

Average Speed ≈ 10.44 meters per second

So, Usain Bolt's average speed during his world-record 100-meter sprint was approximately 10.44 meters per second.
