The figure has the following points

In other to get the distance between McDonald's and Sam Club using Pythagoras theorem
Let the distance between Mcdonald and Sam Club be MS, it follows that
![\begin{gathered} MC^2=5^2+2^2 \\ MC^2=25+4 \\ MC^2=29 \\ MC=\sqrt[]{29} \\ MC=5.385 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/oea0ed1270x24nzsulnf8yp1takdy8kbch.png)
a) Hence, the distance between Mcdonald's and Sam Club is 5.385
b) To get the distance between Mcdonald's and Target using the distance formula
The distance formula is given as
![\begin{gathered} A(x_1,y_1);B(x_2,y_2) \\ AB=\sqrt[]{(y_2-y_1)^2+(x_2-x_1)^2} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/eu5v398muf4atyq0jhotnh257vu5bep0w0.png)
![\begin{gathered} M(1,4) \\ T(6,6) \\ MT=\sqrt[]{(6-4)^2+(6-1)^2} \\ MT=\sqrt[]{2^2+5^2} \\ MT=\sqrt[]{4+25} \\ MT=\sqrt[]{29} \\ MT=5.385 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/2oa8e75zr4v7dzpgamuxrr56wr48ive7ev.png)
b) Hence, the distance between Mcdonald's and Target using the distance formula is 5.385
c) The midpoint formula is given as

The midpoint of between McDonald's and Sam Club is

Hence, the midpoint between McDonald's and Sam Club is (7/2,5)
