In today’s day and age, running has become an increasingly popular sport. People all over the world engage in this activity, whether it is for fun or for competition. And with the growing popularity of running, it is important to educate our students about the fastest runner in the world and how to measure their speed.
The fastest runner in the world is Usain Bolt, who holds the world speed record for running 100 meters, clocking in at 9.58 seconds. However, measuring Bolt’s speed in miles per hour (mph) can be a bit tricky, as he only runs over a distance of 100 meters, which is equivalent to 0.062 miles. Therefore, his speed in mph needs to be calculated by converting meters per second (m/s) into miles per hour.
To do this, teachers can start by explaining that speed is measured by distance divided by time. This means that if Bolt ran 100 meters in 9.58 seconds, we can calculate his speed in m/s by dividing the distance (100 meters) by the time (9.58 seconds). This gives us a speed of 10.44 m/s.
Now, to convert this speed into mph, we need to multiply by a conversion factor. Since 1 meter is equivalent to 0.000621371 miles, we can multiply Bolt’s speed in m/s by this conversion factor to get his speed in mph. This gives us a speed of 23.35 mph!
To help students understand the concept of mph, teachers can use examples from their daily lives. For instance, they can explain that a car may have a top speed of 60 mph, while a fast roller coaster may have a top speed of 70 mph. They can also compare Bolt’s speed to that of other ani
Additionally, teachers can use videos of Bolt’s races to help students visualize his speed. By watching the world record race, students can see how Bolt’s speed is measured and how he moves his body to achieve such incredible speeds. This can give them a better understanding of what it takes to become a world record runner.
