Column inequalities to solve application problems A type a pump, which can pump 1.1 tons of water per minute, can pump water in half an hour. If B type pump is used, it is estimated that it can pump water in 20 minutes. How many tons more water can b type pump pump pump pump than a type pump per minute Use the system of linear inequalities of one variable to solve it! Using a type a pump which can pump 1.1 tons of water per minute to pump the pool can be finished in half an hour; if using B type pump, it is estimated that it can be finished in 20 to 22 minutes. How many tons more water can be pumped by B type pump than a type pump per minute? I'm sorry,

Suppose type B pumps about X tons more water per minute than type A
20(1.1+x)30*1.1
From 1: x0.4
So the solution set of inequality system is 0.55 > x > 0.4
A: about 0.4-0.55 tons of water per minute
