You know that:

- The distance Karen jogged on Wednesday was:


4(3)/(4)mi

- The distance she jogged on Friday was:


3.5mi

Knowing that she jogged 2 fewer miles on Saturday than she jogged on Wednesday, you can determine that the distance she jogged on Saturday was:


4(3)/(4)mi-2mi

To solve the subtraction, you can convert the Mixed number to a Decimal number by dividing the numerator by the denominator and adding the result to the Whole number part:


4+0.75=4.75

Then, the distance she jogged on Saturday is:


4.75mi-2mi=2.75mi

Knowing that value, you can set up the following equation that can be used to calculate how many more miles Karen jogged on Wednesday and Saturday than on Friday:


x=4.75+2.75-3.5

Where "x" represents how many more miles Karen jogged on Wednesday and Saturday than on Friday:

To find how much farther did Karen run on Wednesday and Saturday than on Friday, you have to add the numbers:


\begin{gathered} x=6.75-3.5 \\ x=3.25 \end{gathered}

Therefore, the answers are:


undefined
