    There are 60 seconds in a minute and 60 minutes in an hour.

    Hence:

    1 minute = 60 s
    1 hour = 3600 seconds.

    So the first thing to do is divide your total amount be 3600, and then subtract the remainder, and that is how many hours have passed:

     \frac{2586}{3600} < 1 So no hours pass.

    Note divide your number by 60 to see how many hours pass:

     \frac{2586}{60} = 43.1 , so 43 minutes have passed.

    Now how many seconds? WEll the remainder from the minutes was 0.1. So what is 0.1 minutes in seconds??

     0.1\text{ minutes} = 0.1 \times 60 \text{ seconds} = 6 \text{ seconds}

    So 43 minutes and 6 seconds have passed.
