Question

Hello I need help for this home work by using JAVA language:

You have been assigned as the lead programmer for the World Track and Field Championships! The 100 meter dash is one of the highlights of this competition and is considered by many to demonstrate the world’s fastest human. Your job is to take the top finish time (given in seconds with two digits of precision to the right of the decimal point) for the 100 meter dash and do some conversions to find out how fast the person was traveling in:

· meters per second

· feet per second

· kilometers per hour

· miles per hour

In addition, you must also determine how long it would take the person to run one mile. And finally, you must determine how long it would take the person to run 100 yards.

Your program design should make use of java methods to properly encapsulate variables and processing.

The result of each conversion you perform should be displayed and clearly labeled, as demonstrated in the sample “run” below (NOTE: the actual numeric results are not displayed – that is for you to figure out):

Example run:

Please enter the winning time of the race: 15.00

The person was traveling at a rate of:

x.xx meters per second,

y.yy feet per second,

z.zz kilometers per hour,

y.yy miles per hour,

It would take m minutes and n.nn seconds for the person to run one mile.

It would take t.tt seconds for the person to run 100 yards. Programming Principles I 1/7/2015

It is your job to figure out the conversions necessary to determine the necessary output based on the above (NOTE: it is also your job to format your output in the same style as shown).

Your solution must be designed modularly.

A zip file containing:

_Your java code - class is named Track.java.

_A text file showing three sample runs (capture you output in the jGrasp console window -right-click).

Explanation / Answer

Here I am giving you the source code for the problem. Save it as Track.java and then you can get the sample runs by feeding different input time.

import java.lang.Math; // headers MUST be above the first class
import java.util.*;
// one class needs to have a main() method
public class Track
{
// arguments are passed using the text field below this editor
public static void main(String[] args)
{
double time_to_win,in_mt_sec,in_ft_sec,in_km_hr,in_mile_hr,feet,time_in_1mile,time_in_1mile_min,time_in_1mile_sec,time_in_100yards;
System.out.println("Please enter the winning time of the race:");
Scanner s = new Scanner(System.in);
time_to_win=s.nextDouble();
in_mt_sec=100/time_to_win;
feet=100/3.28;
in_ft_sec=feet/time_to_win;
in_km_hr=in_mt_sec/3.6;
in_mile_hr=in_km_hr/0.62;
time_in_1mile=time_to_win*1609.34/100; //1 mile=1609.34 meters
time_in_1mile_min=time_in_1mile/60;
time_in_1mile_sec=time_in_1mile%60;
time_in_100yards=time_to_win*91.44/100; //100 yards=91.44 meters
System.out.println("The Person was travelling at the rate of:");
System.out.println(in_mt_sec+" meters per second,");
System.out.println(in_ft_sec+" feet per second,");
System.out.println(in_km_hr+" kilometers per hour,");
System.out.println(in_mile_hr+" miles per hour,");
System.out.println("It would take "+time_in_1mile_min+" minutes and "+time_in_1mile_sec+" seconds for the person to run one mile.");
System.out.println("It would take "+time_in_100yards+" seconds for the person to run 100 yards.");
  
}
}
