Answer:
6 days and 18 hours
Explanation:
Given that after 4 days, the workers still have to install 360 chairs, it is expected that as time in days increases, the number of chairs installed increases as well. This is a direct proportionality between both measures.
If after 4 days, the workers still have to install 360 chairs then 600 chairs would be installed in
= 600 * 4/360 days
= 6 2/3 days
= 6 days and 18 hours
