Clarissa cycled at 12 1/2 miles per hour for 2 1/2 hours far did she travel?
A 15
B 25
C 31 1/4
D 10
To find how far Clarissa traveled, we need to multiply her speed (12 1/2 mph) by the time she cycled (2 1/2 hours).
First, convert 12 1/2 to an improper fraction:
12 1/2 = (2 * 2 + 1)/2 = 25/2
Now, multiply the speed (25/2 mph) by the time (2 1/2 hours):
(25/2) * (5/2) = (25 * 5)/(2 * 2) = 125/4
So, Clarissa traveled 125/4 miles.
To make the fraction mixed, divide the numerator by the denominator:
125 ÷ 4 = 31 remainder 1
So, Clarissa traveled 31 1/4 miles.
The correct answer is C) 31 1/4.
To find out how far Clarissa traveled, you can multiply her speed by the time she cycled.
Her speed is 12 1/2 miles per hour, and she cycled for 2 1/2 hours.
To multiply mixed numbers, convert them to improper fractions.
12 1/2 can be written as 25/2, and 2 1/2 can be written as 5/2.
Now, multiply 25/2 by 5/2:
(25/2) * (5/2) = (25 * 5) / (2 * 2) = 125/4.
So Clarissa traveled 125/4 miles.
To simplify the answer, divide the numerator (125) by the denominator (4):
125 ÷ 4 = 31 1/4.
Therefore, Clarissa traveled 31 1/4 miles.
The correct answer is C) 31 1/4.
To find out how far Clarissa traveled, we need to multiply her speed (12 1/2 miles per hour) by the time (2 1/2 hours).
First, we need to convert the mixed numbers into improper fractions.
12 1/2 can be written as 25/2, and 2 1/2 can be written as 5/2.
Now, multiply the fractions:
(25/2) x (5/2) = (25 x 5) / (2 x 2) = 125 / 4
Therefore, Clarissa traveled 125/4 miles.
To simplify this fraction, we can divide the numerator (125) by the denominator (4):
125 ÷ 4 = 31 1/4
So Clarissa traveled 31 1/4 miles.
Therefore, the answer is option C, 31 1/4.
