Solution:
we are given that
Mary ran 4 miles in 37 minutes.
we have been asked to find
how long would it take her to run 11 miles?
Since Mary ran 4 miles in 37 minutes, it mean time taken to run 1 miles can be given by
[tex] t_{1 \ mile}=\frac{37}{4} \ minutes. [/tex]
Hence we can write , time taken in running 11 miles as
[tex] t_{11 \ mile}=\frac{37}{4}*11 \ minutes.\\
\\
t_{11 \ mile}=\frac{407}{4} \ minutes\\
\\
t_{11 \ mile}=101.75 \ minutes\\ [/tex]
