Answer:[tex]\frac{199}{24}[/tex]
Step-by-step explanation:
Given
At the beginning of race you start[tex] 4\frac{5}{8}[/tex] behind your friend .
At the halfway point, you are [tex]3\frac{2}{3}[/tex] feet ahead of your friend.
Therefore change in distance
initially it is [tex]4\frac{5}{8}=\frac{37}{8}[/tex]
at half way it is [tex]3\frac{2}{3}=\frac{11}{3}[/tex]
total change [tex]=\frac{37}{8}+\frac{11}{3}=\frac{199}{24}[/tex]
