Nolan Ryan has been clocked throwing a fastball 100 miles per hour. At that speed, how much time does the batter have to react? The pitcher’s mound is 60 feet 6 inches from home plate.

Answer 1

100 miles/hr x 1hr/3600 sec x 1 mile/5280 ft = 146.66 ft./sec

If the plat is 60.5 feet away, 60/146.66 = .41 seconds
