To find the distance, we can multiply the speed by the time.
12 1/2 miles per hour * 2 1/2 hours = 31 1/4 miles
Therefore, Clarissa traveled 31 1/4 miles.
To find the distance Clarissa traveled, we can use the formula:
Distance = Speed × Time
In this case, Clarissa cycled at a speed of 12 1/2 miles per hour for 2 1/2 hours.
To calculate the distance, convert the mixed number speed into an improper fraction:
12 1/2 = 25/2
Now we can substitute the values into the formula:
Distance = (25/2) × (2 1/2)
To multiply fractions, multiply the numerators and denominators separately:
Distance = (25/2) × (5/2)
Multiply the numerators: 25 × 5 = 125
Multiply the denominators: 2 × 2 = 4
So, the equation becomes:
Distance = 125/4
To simplify the fraction, divide the numerator by the denominator:
Distance = 31 1/4
Therefore, Clarissa traveled a distance of 31 1/4 miles. The correct answer is 31 1/4.
To find the distance Clarissa traveled, we can use the formula distance = speed × time.
Given that Clarissa cycled at 12 1/2 miles per hour for 2 ½ hours, we can substitute these values into the formula:
Distance = 12 1/2 miles/hour × 2 1/2 hours
To multiply fractions, we need to multiply the numerators and then multiply the denominators:
Distance = (25/2) miles/hour × (5/2) hours
Multiplying the numerators gives us 25 × 5 = 125, and multiplying the denominators gives us 2 × 2 = 4. So the calculation becomes:
Distance = 125/4 miles
Converting this into a mixed number, we have:
Distance = 31 1/4 miles
Therefore, Clarissa traveled a distance of 31 1/4 miles.
