with a partner, use a stopwatch or ordinary watch to time how long it takes you to run a specific distance, for example 100 m or around the school. If possible, run 100 m and then compare your time to the world record? What is the difference between your time and your partner's time?

To time how long it takes you and your partner to run a specific distance, such as 100 meters, you will need a stopwatch or an ordinary watch with a second hand.

Here's how you can do it:

1. Start by finding a suitable location to run, such as a track or a flat stretch of road. Measure out a distance of 100 meters using a measuring tape or by checking an online map for a reference point.

2. Make sure both you and your partner have your watches synchronized and set to zero.

3. Stand side by side at the starting point and, on the count of three, start running as fast as you can.

4. As soon as you cross the finish line, stop the stopwatch or note the time on your ordinary watch.

5. Repeat the process a few times to get a more accurate average time. It's essential to give yourselves some rest between each run to avoid fatigue.

Now that you have the times for both you and your partner, you can compare them and calculate the difference between your times.

For example, let's say your time was 15.5 seconds, and your partner's time was 13.7 seconds.

To find the difference, you subtract the slower time from the faster time:

15.5 seconds - 13.7 seconds = 1.8 seconds

So, the difference between your time and your partner's time is 1.8 seconds.

To compare your times to the world record, you can search for the current world record time for the 100-meter sprint—both for men and women. As of my knowledge, as of September 2021, the men's world record set by Usain Bolt is 9.58 seconds, and the women's world record set by Florence Griffith-Joyner is 10.49 seconds.

By comparing these world record times to your own, you can see the significant difference in performance between world-class athletes and yourselves.
