Caroline runs 3 and one half miles in 221 over 4 minutes. How many miles does she run per minute?
14/89
LOL is correct. It is 14/89.
OMG, IT TOOK ME HOURS TRYING TO FIGURE THAT OUT
THANKSTHANKSTHANKS
To find out how many miles Caroline runs per minute, we need to divide the total number of miles she runs by the total number of minutes she takes.
First, let's convert the mixed number 3 and one half to a fraction. The mixed number 3 and one half can be represented as 3 + 1/2, which is equal to 6/2 + 1/2 = 7/2.
So Caroline runs a total of 7/2 miles.
Next, let's convert the time from a mixed number to a fraction. The mixed number 221 over 4 can be converted to a fraction by multiplying the whole number (55) by the denominator (4) and then adding the numerator (1):
(55 * 4 + 1)/4 = 221/4.
So, Caroline takes a total of 221/4 minutes.
Now, to find out how many miles she runs per minute, we divide the total distance (7/2 miles) by the total time (221/4 minutes):
(7/2) / (221/4) = (7/2) * (4/221).
When we multiply these two fractions, we get:
28/442 = 14/221.
Therefore, Caroline runs approximately 14/221 miles per minute.
(7/2)mi / (221/4) min
= 7/2 * 4/221 mi/min
= 14/221 mi/min
