Procedure
We were being vectored for a visual approach to Runway 12R. The final published speed on the NITZR2 arrival is 230 KTS; and we were maintaining that speed. ATC gave us a descent to 4;000 [feet]; and then a base turn and a descent to 3;000 [feet]. Somewhere between 4;000 and 3;000 feet; ATC said 'Aircraft X you have left Class Bravo airspace and will reenter in around a mile.' I acknowledged the call and the pilot flying continued calling for configuration changes as we prepared to land. Our base turn was well before DOLEE on the arrival; so we couldn't have been under the MSP Class Bravo airspace for more than a few seconds; but we were at 230 knots.
Pilot reported being told by ATC that they have left the class Bravo airspace but will enter again in around a mile. Pilot acknowledged the call and felt they could not have been out of the Class Bravo for more than a few seconds; but were at 230 knots while under it.
