5. code for calculate time duration in which a 340m

long train can pass 160m long tunnel at speed 45 km/hr

package com.google;

public class Ass5 {

public static void main(String[] args) {

int trainLength=340;//340 m long train

double speed=45.0;//45 km/hr speed of train

int tunnel=160; //160m long tunnel

/*

* Here we have given speed in km/hr and length of train and tunnel in m unit...

* first we have to convert km/hr in m/s

* 45 km/hr= 45* 1000/3600 m/s

* Speed= 25/2 m/s

* Total distance to cover (340+160)m= 500m

* time = distance/speed

* 500/ (25/2)

* 500*(2/25)

* 40 seconds

* */

speed=(double) speed*(1000/3600.0);

int distance=tunnel+trainLength;

double time=distance/speed;

System.out.println(" Time required :"+ time+" Seconds");
