Calculate the duration or expected drive time between two latitude, longitude points

I want to calculate the duration between two points. I know there is Google Maps API but I don't want to use it, I need an equation to do it. There is one calculate the distance I need one for the duration of drive time.

public String getTimeTaken(Location source, Location dest) {


    double meter = source.distanceTo(dest);

    double kms = meter / 1000;

    double kms_per_min = 0.5;

    double mins_taken = kms / kms_per_min;

    int totalMinutes = (int) mins_taken;

    Log.d("ResponseT","meter :"+meter+ " kms : "+kms+" mins :"+mins_taken);

    if (totalMinutes<60)
    {
        return ""+totalMinutes+" mins";
    }else {
        String minutes = Integer.toString(totalMinutes % 60);
        minutes = minutes.length() == 1 ? "0" + minutes : minutes;
        return (totalMinutes / 60) + " hour " + minutes +"mins";

    }


}

call this method like

 binding.estimationTime.setText("" + getTimeTaken(deliveryboy_location, userLocation) );

Well, take a guess how you can achieve that without the knowledge of

  • roads
  • speed limit
  • traffic
  • graphs

Pretty hard. I see 2 solutions:

Use the Google Distance Matrix API

https://developers.google.com/maps/documentation/distance-matrix/start

https://maps.googleapis.com/maps/api/distancematrix/json?origins=my_origins&destinations=my_destinations&departure_time=now

Estimate with Speed

Location loc1 = new Location("");
loc1.setLatitude(lat1);
loc1.setLongitude(lon1);

Location loc2 = new Location("");
loc2.setLatitude(lat2);
loc2.setLongitude(lon2);

float distance = loc1.distanceTo(loc2);

int speed=30;
float time = distance/speed;
