100 meters/15.2 seconds 100 meters = 0.0621371192 miles 15.2 seconds = 0.00422222222 hours 100 m/15.2s = 14.7166861 mph average
If someone or something covers 200 meters in 23 seconds, the average speed is about 19.45162 miles per hour. To solve, look at what you have to start with. You have 200 meters per 23 seconds. That's 200meters/23seconds in "math speak" here. Every mile has about 1609.344 meters in it. You already know that each minute has 60 seconds in it, and each hour has 60 minutes in it. Here's the setup: (200meters/23seconds) x (1mile/1609.344meters) x (1 minute/60seconds) x (60minutes/1hour) = Grab your calculator and have at it. Note that all the units cancel out and you're left with miles/hours or miles over hours or miles per hour. Piece of cake.
200 meters in 36 seconds is equivalent to a speed of approximately 18.18 miles per hour.
12 miles per hour-seconds = 5.364 meters per second2

To convert 4.4 miles per hour per second to meters per second squared, first convert 4.4 miles to meters (1 mile = 1609.34 meters) and 1 hour to seconds (1 hour = 3600 seconds). Then divide the speed in meters per second by the time in seconds squared to get the acceleration in meters per second squared.
Running 100 meters in 6.13 seconds is equivalent to running at a speed of approximately 22.66 miles per hour.
Traveling 100 meters in 80 seconds equates to an average speed of 2.79 miles per hour.
