Answer:
C
Step-by-step explanation:
We have the distance Anna walks, which is 9 5/8 miles and the time she takes to walk that far is 2 3/4 hours. Velocity is defined as distance over time:
Therefore we can calcuate her velocity which is speed. We change the numbers to fractions
[tex]V=(77/8)/(11/4)=(77/8)*(4/11)=77/22[/te]
77/22 is 3 1/2 so the answer is C
