this is just a series question....you would have
:
1,2,4,8,16,32... each time it doubles
:
where n equals 0 to 45
:
we have 180 total minutes.......divided by 4 minute segments= 45 doublings

Try this!
Starting with one cell at time zero and doubling every 4 minutes:
Time-----------Cells
..0(4).........1 -->
..1(4).........2 -->
..2(4).........4 -->
..3(4).........8 -->
.
.
..45(4).........
So you need to know how many times this doubling will take place in 3 hours. Divide 3 hours, that's 180 minutes by 4 to get 45 times, (n = 45) so at the end of 3 hours, there will be cells.
