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?

Result

x =  1440 hl

Solution:

p1=1800/3/5=120 x=2⋅ 6⋅ p1=2⋅ 6⋅ 120=1440 hlp_{1}=1800/3/5=120 \ \\ x=2 \cdot \ 6 \cdot \ p_{1}=2 \cdot \ 6 \cdot \ 120=1440 \ \text{hl}
