117 Mr. Turtle, Mrs. Squirrel and Ms. Pigeon work at the Magic Forest's post office. Mr. Turtle can
insens350 [35]

Using proportions, it is found that the same job will take Mrs. Squirrel 6 hours.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The times are given as follows:

  • Mrs. Squirrel: x.
  • Mr. Turtle: 3 days.
  • Mr. Pigeon: 30 minutes = Half an hour = 1/48 day.

The ratios are as follows:

Turtle/Squirrel = Squirrel/Pigeon.

Hence:

\frac{3}{x} = \frac{x}{\frac{1}{48}}

x^2 = \frac{3}{48}

x^2 = \frac{1}{16}

x = \sqrt{\frac{1}{16}}

x = 1/4.

It takes 1/4 of a day for Mrs. Squirrel to do the job, hence 1/4 x 24 hours = 6 hours.
