Josephine can correct her students' test papers in 9 hours, but if her teacher's assistant helps, it would take them 7 hours. Ho

kirill [66]

Using the together rate, it is found that it would take the assistant 31 hours and 30 minutes to do it alone.

<h3>What is the together rate?</h3>

It is the sum of each separate rate.

In this problem, the rates are given as follows:

Josephine: 1/9.

Assistant: 1/x.

Together: 1/7.

Hence:

$\frac{1}{9} + \frac{1}{x} = \frac{1}{7}$

$\frac{x + 9}{9x} = \frac{1}{7}$

$9x = 7x + 63$

2x = 63

x = 31.5.

It would take the assistant 31 hours and 30 minutes to do it alone.
