> I've done it in Excel and it's not hard to do if you have some spreadsheet software. You first have to calculate the feet per second a ball travels at each pitch speed. For example, a 90 mph fastball travels 132 feet per second. Then you can plug in different distances and calculate how long it takes for a pitch to reach the plate.

so 63 Mph is about 80...yes/no?
