3. To break the school's record, the girls' time had to be faster than 12 2/5 minutes.

Did the girls break the record? If so, how much faster were
they? If not, how much slower were they?

Using improper fractions, it is found that they broke the record and were 0.8 minutes faster.

How to convert improper fractions to standard fractions?

The conversion is made according to the following formula:

[tex]a\frac{b}{c} = a + \frac{b}{c} = \frac{ac + b}{c}[/tex]

In this problem, the time had to be faster than [tex]12\frac{2}{5}[/tex] minutes, which is a time in minutes of:

[tex]12\frac{2}{5} = 12 + \frac{2}{5} = 12 + 0.4 = 12.4[/tex]

Researching the problem on the internet, it is found that their time was of [tex]11\frac{3}{5}[/tex] minutes, hence:

[tex]11 + \frac{3}{5} = 11 + \frac{3}{5} = 11 + 0.6 = 11.6[/tex]

11.6 < 12.4, hence they broke the record.

12.4 - 11.6 = 0.8, hence they were 0.8 minutes faster.
