60.5/.4=151.25 FEET PER SECOND.
3600 SECONDS PER HOUR.
151.25*3600=544.500 FEET PER HOUR
5280 FEET PER MILE
544.500/5280=103.125 MPH FOR THE SPEED OF THE BALL.

You know that there are 5280 feet in a mile.
You can find the distance in miles that the ball traveled from the pitchers mound to the plate by dividing.
60.5%2F5280=.011458333
now you find how many hours elapsed
.4%2F60%2F60=.000111111 note that 60 seconds in a min and 60 mins in an hour
now by dividing the time by the distance you can find the mph of the ball
.011458333%2F.0001111111=103.125
the ball traveled aprox 103 mph
