第一章第十题（以英里计的平均速度）(Average speed in miles)

• 1.10（以英里计的平均速度）假设一个跑步者45分30秒跑了14千米。编写一个程序显示以每小时多少英里为单位的平均速度值。（注意，1英里约等于1.6千米。）
  1.10 (Average speed in miles) Assume that a runner runs 15 kilometers in 50 minutes and 30 seconds. Write a program that displays the average speed in miles per hour. (Note that 1 mile is 1.6 kilometers.)
• 参考代码：

package chapter01;public class Code_10 {
    public static void main(String[] args) {
    final int running_time = 45 * 60 + 30;final int running_meters = 14 * 1000;double running_miles = 1.0 * running_meters / 1600;System.out.println("The speed of the runner is (miles per hour) : " + (8.75 / 2730 * 3600));}
}

• 结果显示：

The speed of the runner is (miles per hour) : 11.538461538461538Process finished with exit code 0
