If the pitchers mound is 60 ft from home plate how many seconds does it take a 75-mph pitch to reach home plate?

75 miles per hour is about 110 feet per second. So a pitch thrown at that speed will reach home plate in a little more than half a second (about .55 seconds). A pitch thrown at 90 MPH will reach the batter in about a tenth of a second less (.45 seconds).
