Pumps

Five pumps pumped 1,800 hl of water for 3 hours. How many hectoliters of water pump same two powerful pumps for six hours?

Correct answer:

x =  1440 hl

Step-by-step explanation:

$$\begin{gathered} n_1=5 \\ {n}_2=2 \\ {t}_1=3\text{ h } \\ {t}_2=6\text{ h } \\ {p}_1=1800\mathrm{/}(t_1\cdot n_1)=1800\mathrm{/}(3\cdot 5)=120\text{ hl/h } \\ x=n_2\cdot t_2\cdot p_1=2\cdot 6\cdot 120=1440\text{ hl} \end{gathered}$$
