The time that it took Ella to finish the race is: 37.6 minutes.
Since Miranda finished the race 9 1/10 minutes sooner, to find Miranda's time we need to subtract 9 1/10 from Ella's time of 37.6 minutes.
Miranda's time:
[tex]37.6-9\frac{1}{10}[/tex]To solve the problem it is easier if we convert 9 1/10 to a decimal number. Since 1/10 is equal to .1, the equivalent value of 9 1/10 is:
[tex]9\frac{1}{10}=9.1[/tex]Updating the expression to find Miranda's time:
[tex]37.6-9.1[/tex]And the result of the subtraction is:
[tex]28.5[/tex]It took Miranda 28.5 minutes to finish the race. Since this value is not one of our options, the answer is D. not here
