In the baseball the pitcher's mound is 60.5 feet from home plate.The strike zone,or distance across the plate,is 17 inches.The time it takes for a baseball to reach home plate can be determined by diving the distance the ball travels by the speed at which the pitcher throws the baseball.

Question:If a pitcher throws a baseball at 90 miles per hour,how many seconds does it take for the baseball to reach home plate?How long is the ball in the strike zone?

能帮忙解一下就更谢谢啦~~

在棒球里，投手土堆（投手站的地方）离本垒60.5英尺。击球区，或击球手离本垒是17英寸。棒球从投手到本垒的时间可以由投手的投球速度与距离算出。

问题：如果投手的球速是90英里每小时，那么从投手到本垒要多久？到击球区要多久？（也就是到捕手要多久）
s=vt
s1=60.5英尺 v=90mile/hr s2=60.5英尺+17英寸
t=s/v t1=0.4583(秒） t2(到捕手）=0.4691（秒）

要了解棒球知识，还要换算，够麻烦的……
