How much time do you need only for driving?
+2070%2F90+=+23+ hrs
+23%2F4+=+5.75+
There are 5 one hr breaks
--------------------------
There are 5 of the 4 hr driving periods
There is one 3 hr driving period at the end of the drive
There are 5 one hr breaks
+5%2A4+%2B+3+%2B+5+=+28+ hrs total time
----------------------------------
This is the sequence:
4(1) 4(1) 4(1) 4(1) 4(1) 3
