Answer 1

Do you mean you want to convert it to min and secs, if yes then:

function readableDuration(seconds) {
    sec = Math.floor( seconds );    
    min = Math.floor( sec / 60 );
    min = min >= 10 ? min : '0' + min;    
    sec = Math.floor( sec % 60 );
    sec = sec >= 10 ? sec : '0' + sec;    
    return min + ':' + sec;
}
console.log( readableDuration(351.234) ); // 05:51
