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.
