Hectares of forest

12 workers plant 24 ha of forest in 6 days. In how many days will 15 people and 12 people plant the same area?

Result

t12 =  6 d
t15 =  4.8 d

Solution:

t12=12 612=6 dt_{12}=\dfrac{ 12 \cdot \ 6 }{ 12 }=6 \ \text{d}
t15=12 615=245=4.8 dt_{15}=\dfrac{ 12 \cdot \ 6 }{ 15 }=\dfrac{ 24 }{ 5 }=4.8 \ \text{d}



Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
