Figure 1 shows a representational pie chart of the cell cycle for a cultured human epithelial cell.

Figure 1: Representational pie chart of a cell cycle.

The total cell cycle for these cells takes 22 hours. The 'Interphase (G1 G_1\,G1​ and S phases)' stage takes 750 minutes. The 'Interphase (G2 G_2\,G2​ phase)' sector forms a right angle (exactly 90∘90^\circ90∘).

Calculate the time taken for the 'M-phase (Mitosis and Cytokinesis)' of this cell cycle in minutes.
