Answer:28.26
Step-by-step explanation:9 x 3.14
running at the same rate?
We want to create a proportion with minutes over miles for each person. The proportion for this problem is shown below.
30 minutes / 4 miles = 56 minutes / 7 miles
To find out if these people are running at the same rate, we can cross-multiply.
224 = 210
Because 224 and 210 are not equivalent, the people are not running at the same rate.
Hope this helps!! :)
