Today, we went outside and measured our speed. First we learned how to calculate average speed. We now know that:
We then went outside to perform the following tasks:
– mark off 70 meters (we didn’t have enough space to run 100 meters)
– run 70 meters as fast as we could
– record our time
– calculate out average speed
For fun, we then calculated Usain Bolt’s average speed when he ran the 100 meters in the world record time of 9.58 seconds. During Bolt’s record run, he covered an amazing 10.44 meters every second!
