## converting a figure into hours!

converting a figure into hours! simple really

I got a figure of 70.86 which is calculation to 24 hours so its 70 hours something.
So if it was 12 pm on the tuesday plus the amount above, what time and day would it be????

 How many hours is 12pm Wednesday?

There are 60 minutes in an hour, so .86 hours is (.86)(60)= 51.6 minutes. There are 60 seconds in a minute so .6 minutes is (.6)(60)= 36 seconds. 70.86 hours is three days and 22 hours, 51 minutes, 36 seconds, so starting from noon, Tuesday, you add two days, to noon Thursday, then, since noon is already half a day, add one more day for the additional 12 hours, ending at 10:51:36 AM Friday. (Silly arithmetic error corrected thanks to oay.)

Not quite.

Your first sentence is arithmetically incorrect, so you are out by a day. The time is correct, but it is actually on the Friday.

Hi HoI,

If you're going to edit your post to correct it, it may be wise to correct all of it! eg...
