On a hike, Peter and Jamie walked 3one-eighth hours at 2one-half miles per hour. How far did they walk?
A. 7thirteen-sixteenths miles
B. 1one-fourth miles
C. 6Start Fraction 1 over 16 End Fraction miles
D. 7three-fourths miles
To solve this problem, we can use the formula: distance = rate x time.
Peter and Jamie walked for 3 1/8 hours at a rate of 2 1/2 miles per hour.
First, let's convert the mixed numbers to improper fractions:
3 1/8 = 25/8
2 1/2 = 5/2
Now we can plug in the values into the formula:
distance = (5/2) x (25/8)
Simplifying:
distance = 25/4
Converting the improper fraction back to a mixed number:
distance = 6 1/4
Therefore, they walked 6 1/4 miles.
The answer is (B) 1 1/4 miles.
