A quick look at my old edition of Strickberger has a couple of representative
numbers: in E. coli, transcription of one enzyme at 37 deg. C was about
28 nucleotides/sec; 30 ribosomes then translate the message at about
7 AA/sec each. He gives several other examples to illustrate the range,
but it looks like these events are fairly fast, on the order of several
minutes.

Whatever the generation time of the organism happens to be.
These are pretty easy answers to pull out of just about any reasonable
genetics/mol bio textbook...why do you ask?
