hello,
to solve this question, we can keep the time in minutes, because all of them are in the same unit of time .
Now, we need to write the informations as a fraction, following this example:
[tex]\frac{\text{number of sit-up}}{\text{ time spent}}[/tex]
So, let's solve each one:
Casey:
[tex]\frac{93}{3}=\text{ }31\text{ per minute}[/tex]
D'Andrea:
[tex]\frac{176}{4}=\text{ 44 per minute}[/tex]
Eden:
[tex]\frac{215}{5}=\text{ 43 per minute}[/tex]
Flores:
[tex]\frac{111}{3}=\text{ 37 per minute}[/tex]
So, D'Andrea did the most sit-ups per minute.
