Question

Caroline runs 3 1/2 miles in 22 1/4 minutes. How many miles does she run per minute?
A. 3/22
B. 62/221
C. 14/89
D. 4/39

Answer 1

For calculating this, you should divide minutes value from miles

It would be 3 1/2 / 22 1/4 = 7/2 / 89/4

you can write it as:

7/2 * 4/89 = 14/89

SO, OPTION C is your answer

Answer 2

Answer:- C is the right option.Distance in miles she traveled per minute=$=\frac{14}{89}\ miles\ per\ minute$

Explanation:-

Given: Distance traveled by Caroline $=3\frac{1}{2}\ miles=\frac{7}{2}\ miles$

Time taken$=22\frac{1}{4}\ minutes=\frac{89}{4}\ minutes$

Distance in miles she traveled per minute$=\frac{distance}{time}\\=\frac{\frac{7}{2}}{\frac{89}{4}}\\\\=\frac{7\times4}{89\times2}\\\\=\frac{14}{89}\ miles\ per\ minute$

Therefore, Distance in miles she traveled per minute=$=\frac{14}{89}\ miles\ per\ minute$
