Atank of water holding 528 kl of water begins to empty at a rate of 10 kl/min. at the same time, another tank, which is empty, begins to fill at a rate of 14 kl/min. let k represent the number of kiloliters of water and let t represent time in minutes. the system models this situation. how long will it take for the tanks to hold equal amounts of water, and how much water will that be? k = 528 – 10t. k = 14t.
it will take minutes__ for both tanks to hold equal amounts of water. they will each hold__ kiloliters.
