# Five tractors

Five tractors plow field in 4.8 hours. How long plow this field if after 1.5 hours of work two tractors went to a different field?

Correct result:

x =  7 h

#### Solution:

$\frac{1.5\cdot 5}{4.8\cdot 5}+\frac{\left(x-1.5\right)\cdot 3}{4.8\cdot 5}=1$

1.5•5/(4.8•5) + (x-1.5)•3/(4.8•5)=1

0.125x = 0.875

x = 7
