Packed Absorption Tower

Struggling to solve this problem below. Any insight or direction would be greatly appreciated.

Effluent air stream contains 5.4% SO2 by volume. It's desired to reduce this concentration to 1000 ppm by passing the gas stream through a packed tower (counter flow absorber). Inlet gas flow rate is 1000 ft^3/min measured at 1 atm and 68 degrees F. The equilibrium of SO2 in water is represented by y = 30x. What is the approximate minimum amount of water required as a solvent in ft^3/min?
