Step-by-step explanation:
2 x 4 = 8
2 x 3 = 6
<span>Let x=amount of time it takes both pipes draining together to empty the pool
First pipe empties at the rate of 540,000/150=3600 liters/min
Second pipe empties at the rate of 540,000/225=2400 liters/min
Together, both pipes empties at the rate of 3600+2400=6000 liters/min, so our equation to solve is:
6000*x=540000 </span>
(2,0)(0,2
(-1,-3)(-3,-1)
(-1,3) (1,0)
