Question

I have a variable time = (float)route / (float)speed; which is 3,96. I wondering if there is some methods to convert this number automatically in to the time? For example 3,96 i need to transform into 4,36.

Answer 1

Actually the “time” you’re getting is not: 3 hours and 96 minutes, but it is really: 3 hours and 0.96 (or 96%) of one hour:

            int route = 396; // [km]
            int speed = 100; // [km/h]
            float time = (float) route / (float) speed;
            int hours = (int) time;
            int minutes = (int) (60 * (time - hours));
            System.out.println(hours + "h " + minutes + "m");

Output:

3h 57m
