4*10 = 40

7:4 walls = 10:8 people =M:40 minutes

M = (7/4) / (10/8) x 40

M = 56 minutes.

145,712 x 0.35 =50,999 people that are very rich and wealthy.

145,712 x o.50 =72,856 people that are middle-class.

145,712 - [50,999 + 72,856] =21,857 people that are homeless, which is 15% of the city population!![I hope this is not true!!].
