John Isner serves 140 miles per hour. How fast is that in feet per second?

Answer 2

Explanation:

140 * 5280 = ???

(Miles) * (Feet)

??? * 3600 = ???

(answer from before) * (seconds in a hour)

You need to convert it. When converting to a smaller unit multiply. Since there are 3,600 seconds in an hour, multiply you answer to that.

Hope this helps! I cannot give you that answer, but here's a explanation on how to solve it. :)
