Question

Using Java:

You will write a program that will ask the runner's name, how far he/she ran, and how long it took. You will then calculate how fast the runner actually ran. Then you will calculate how long it would take to run a 10K, and how long it would take to run a marathon if the runner were able to maintain this pace. You will also show the runner what his/her training pace is Ask for the runner's name Ask She runner to enter a floating point number for the number of miles ran, like 3.6, or 9.5 3 Then ask for the number of hours, minutes, and seconds it took to run. What is your first name?//user enters Pheidippides How far did you run today? 1.5//user enters 1.5 miles user enters 0 hours How long did it take? hours: 0//user enters 12 minutes seconds:0//user enters 0 seconds Hi Pheidippides, Your pace is 8:0 (minutes seconds) At this rate your marathon time would be 3:29:36 and your 10K time would be 0:49:41 Good luck with your training! Definitions: 10K - a 10 kilometer race. marathon a 26.2 mile long race. 1 mile- 1.61 kilometres pace - how long it takes (in minutes and seconds to run 1 mile. Example: if I can run 1 mile in 5 minutes and 23 seconds, then my pace is 5:23.

   public static void main(String args[]){

       System.out.println("At this rate your marathon time would be " + h + ":" + m + ":" + s);
   }
  
static void print10k(float pace){
      
       int h=0,m=0,s=0;

       float ten_k_time= (float) pace * (10f/1.61f) ; //10k Time is calculated

Sample run:

What is your first name?
Pheidippides
How far did you run today?
1.5
How long did it take? hours:
0
minutes:
12
seconds:
0
Hi Pheidippides,
Your marathon time is 8:0 (minutes:seconds)
At this rate your marathon time would be 3:29:36
and your 10k time would be 0:49:41
Good luck with your training!

Sample run 2:

What is your first name?
kanika
How far did you run today?
5
How long did it take? hours:
1
minutes:
0
seconds:
0
Hi kanika,
Your marathon time is 12:0 (minutes:seconds)
At this rate your marathon time would be 5:14:24
and your 10k time would be 1:14:32
Good luck with your training!
