24 divides into 70 two times with remainder 22: 70= 2(24)+ 22. 12 divides into 22 once with remainder 10: 22= 12+ 10. 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.)

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

Ouch! For some reason, on that whole problem, I was thinking "75" rather than "70". I will edit my first post. Thanks.

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