Hi Friend,

Try the following code:

import java.util.*;
import java.text.*;

class DistanceTravelledbyBoat{

public static void main(String[] args){
DecimalFormat df = new DecimalFormat("##.00");
Scanner input=new Scanner(System.in);
System.out.print("Enter width of river: ");
double width=input.nextDouble();
System.out.print("Enter boat's speed perpendicular to river: ");
double boatspeed=input.nextDouble();
System.out.print("Enter river's speed: ");
double riverspeed=input.nextDouble();
double a=width;
double bs=boatspeed;
double c=0;
double t=a/bs;
double rs=riverspeed;
double b=t*rs;
double distance=c*c;
double BB=b*b;
double AA=a*a;
distance=AA+BB;
System.out.println("Distance boat travels: "+df.format(distance));
}
}

Thanks
