I think you need to allow at least 45 minutes. If everything times out well, you could make it in 30 minutes, but if you get to the bus stop at CBR and just miss a bus, that will hold you up. Then if you get to the MK and just miss a monorail, that will take more time.
So that was a long-wided way of saying: best case is 25 minutes, worst case is about 50 minutes.
Or...if you take a taxi, 10-15 minutes tops.
