4hr +(.76hr(60min/hr))

4hr + 45.6 min

4hr+45min+(.6min(60sec/min))

4hr+45min+36sec

4:45:36

Oh, if you really only wanted min and sec without hours...

4hr(60min/hr)+45min+36sec

240min+45min+36sec

285min+36sec
4.76 hours times 60 minutes gives 285.6 minutes. We already have 285 minutes. 60% of 1 minute is 36 seconds, so the answer is 285 minutes and 36 seconds. :D
