# Painters

Six of the painters paint 90 m of fence in five hours.
For how long would the 4 painters paint a 45 meter fence?
How many meters fence painted painters 5 for two hours?

Result

a =  3.75 d
b =  30 m

#### Solution:

$x=90 / 6 / 5=3 \ \\ a=45/(4 \cdot \ x)=45/(4 \cdot \ 3)=\dfrac{ 15 }{ 4 }=3.75 \ \text{d}$
$b=x \cdot \ 5 \cdot \ 2=3 \cdot \ 5 \cdot \ 2=30 \ \text{m}$
