We will have the following:
*We determine by replacing the values stated in the following arrangement:
[tex]t\cdot(r_1+r_2)=170[/tex]That is:
*First set:
[tex](2h)(35mi/h+40mi/h)=150mi[/tex]So, the first set is not.
*Second set:
[tex](2h)(45mi/h+40mi/h)=170mi[/tex]So, the rates were either Nicole was moving at 45 mi/h while Kim was moving at 40 mi/h. [Third option]
