The time it will take Kelsey to paint the entire room is:

<h2>Step-by-step explanation:</h2>

It is given that:

Kelsey painted one fourth of her bedroom in three seventh of an hour.

This means that:

1/4 of bedroom takes 3/7 of an hour

This means that the whole of the bedroom will take 4 times the time it took to cover 1/4 th of bedroom.

i.e. it will take:

$\dfac{3}{7}\times 4\\\\\\=\dfrac{12}{7}\ hour$

Hence, the total time it will take to paint the whole room is:

twelve over seven hours
