Two companies

The family ordered two companies to modify the garden. The first would be done in 20 days, the second would take 40% less time. How long will they work together if the second company started working when the first worked for 4 days?

Correct result:

t =  6 d

Solution:

 4/20+t (1/20+1/(2040/100 20))=1  13.333333t=80  t=6=6 d
