INTERPRET, \( 41-1) \) A fuel distribution company has four tanks and several tankers, which unload or load fuel depending on the company's logistical needs. At the moment: TANK A: Contains 6000 lieres and is connected to two rankers that unload into the rank at \( 40 \mathrm{~L} / \mathrm{min} \) and \( 30 \mathrm{~L} / \mathrm{min} \), respectively. TANK B: Contains 6000 litres and is connected to one tanker that loads at \( 30 \mathrm{~L} / \mathrm{min} \) and another that unloads at \( 40 \mathrm{~L} / \mathrm{min} \). TANK C: Contained 6000 litres half an hour ago, when a ranker was connected to it that unloaded at \( 50 \mathrm{~L} / \mathrm{min} \). TANK D: Contains 6000 litres and is waiting for a ranker due to arrive in 10 minutes which will unload at \( 50 \mathrm{~L} / \mathrm{min} \). a) How many litres will there be in each tank 20 minutes from now? b) If \( L \) is the amounc of fuel, in litres, that a tank will contain after \( m \) minutes, match each tank to the right expression. (1) \( L=6000+70 \cdot m \) (2) \( L=6000+50 \cdot(m+30) \) (3) \( L=6000-10 \cdot m \) (4) If \( m<10 \rightarrow L=6000 \) If \( m \geq 10 \rightarrow L=6000+50 \cdot(m-10) \)

In 20 minutes, we can evaluate the situation in each tank. For Tank A, with two tankers unloading at totals of \(70 \mathrm{~L/min}\), it will decrease by \(1400\) litres, leading to \(4600\) litres remaining. Tank B, with one that loads and another that unloads, will see a net decrease of \(10\) litres, leaving \(5990\) litres. Meanwhile, Tank C, which has already been affected by a \(50 \mathrm{~L/min}\) offloading for the past \(30\) minutes, has completely unloaded and now sits at \(0\) litres. Lastly, Tank D, which just started unloading at \(50 \mathrm{~L/min}\) will have \(1000\) litres after \(20\) minutes. To match the tanks with the correct expressions based on their behaviour over time: - Tank A corresponds to \(L=6000-10 \cdot m\) (3), showing a decrease due to both tankers unloading. - Tank B fits \(L=6000+70 \cdot m\) (1), combining the effect of the loading and unloading tankers. - Tank C matches \(L=6000+50 \cdot(m+30)\) (2) since it reflects prior unloading. - Tank D corresponds to the conditional expression (4), as it doesn’t start unloading until the tanker arrives in 10 minutes.
