* 15.3 in 100 meters is a measurement of time, not distance. It means it took 15.3 seconds to cover 100 meters.
* MPH (miles per hour) is a measure of speed, which is distance traveled over time.
To convert this time to speed in mph, you need to know the distance covered in miles.
Here's how you can calculate it:
1. Convert meters to miles: 100 meters is approximately 0.0621371 miles.
2. Calculate speed in meters per second: Divide the distance (100 meters) by the time (15.3 seconds): 100 / 15.3 ≈ 6.54 meters per second.
3. Convert meters per second to miles per hour: Multiply the speed in meters per second by 2.23694: 6.54 * 2.23694 ≈ 14.6 mph.
Therefore, if someone runs 100 meters in 15.3 seconds, their speed is approximately 14.6 mph.
