Date & Time

[Joe]

Been trying all day


This is what I have

=F4-(C4+8*INT(C4/10))/24
Give a date that shows when I would have to leave to arrive at a pre
determined date taking into account speed & distance. Driving for 10 hrs and
resting for 8hrs, with cell formatted for DATE


=F4-(C4+8*INT(C4/10))/24 gives the time I would have to leave to
arrive at a pre determined time taking into account speed & distance.
Driving for 10 hrs and resting for 8hrs with cell formatted for TIME

e.g.... F4 = del date 1/1/03
C4 is hrs to drive ( 1000 mi @ 70 mph)
result = a leave time & date of 12/31/02, 9:42 Am
I thought by rearranging the formula some and adding the NOW() argument(?)
I could get it to show the time & date I would arrive at a pre determined
distance traveling at 70mph. It didn't work, Guess I should have paid better
attention to those if a train leaves station A traveling at........ problems
in school! What I was trying to do was get the sheet to work in reverse. I
think it was Robert or Chip who came up with the formula previously.

Anyone have any suggestions?

TIA Joe

Joe,

please refrain from multiposting. Crosspost instead if needed, I answered
this question in the newusers NG

maybe you want this instead

=IF(C4/70<=10,NOW()+(C4/70/24),NOW()+(C4/70/24+8/24))

meaning if the driving time equals or is less than 10 hours no need for 8
hours rest but after 10 hours add 8 hours. The latter formula counts from
now and add the time it takes to drive a pre defined milage in C4, if the
mileage is less or equal than 700 then just add the driving time, if greater
add the driving time plus 8 hours

format as mm/dd/yy hh:mm
