The replication cycle can be defined in terms of two constants: C and D

C is the fixed time of 40 minutes required to replicate the entire E.coli chromosome. Its duration corresponds to a rate of replication fork movement of 50,000 bp/minute.

D is the fixed time of 20 minutes that elapses between the completion of a round of replication and the cell division with which it is connected. This period may represent the time required to assemblethe components needed for division.
