The distance from the pitcher's mound to home plate is 60.5 feet. If the ball would be released exactly from the pitcher's mound, it would take approximately 0.43 seconds. But, if you don't want to count that last part of the windup which takes place from the pitcher's mound until the ball is released from the hand, assuming that that distance is about 5 ft, then it takes approximately 0.4 seconds to reach home plate.

We know that an object traveling 90 MPH would travel 7920 feet (1.5 miles) in 60 seconds. Therefore, we can set up the equasion 7920/60 = 60.5/X X = .458 It would take an object traveling 90 MPH .458 seconds to travel 60 feet, 6 inches. It should also be mentioned that pitchers generally release the ball closer to home plate than 60 feet, 6 inches. How much closer depends on the height and release point of the pitcher at the time.
