Anna hiked 95⁄8 miles in 23⁄4 hours. How fast did she walk overall? A. 31⁄4 miles per hour B. 35⁄8 miles per hour C. 31⁄2 miles per hour D. 31⁄3 miles per hour
2 answers:
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
Answer:
C. 3 1/2 miles per hour
Step-by-step explanation:
I just converted the fractions to decimal form.
5/8 = 0.625 9 + 0.625 = 9.625
3/4 = 0.75 2 + 0.75 = 2.75
Now divide the 2 numbers:
9.625 / 2.75 = 3.5
Finally, convert the decimal back to a fraction:
3.5 = 3 1/2
Hope this helps!
