# Boots

Master shoemaker has three apprentices. First do one pair of boots for two days, second for 1 day, third on 1.5 day. If they worked together, for how long it would take made a couple of boots?

Correct result:

x =  11.077 h

#### Solution:

$\ \\ (1/2+1/1+1/1.5)(x/24)=1 \ \\ \ \\ (1/2+1/1+1/1.5) \cdot \ (x/24)=1 \ \\ \ \\ 2.166667x=24 \ \\ \ \\ x=\dfrac{ 144 }{ 13 } \doteq 11.076923=11.077 \ \text{h}$
