Answer:

C

Step-by-step explanation:

time is directly proportional to the number of problems in the set

=> x = ky

k = constant of proportionality

when k = 12

x = 12y

by making y the subject, we divide both sides by 12

=> y = x/12

Geri ran in a marathon race. It took her 3 hours and 28 minutes to run 26 miles. How many minutes did it take her to run 1 mile
nadya68 [22]

1 hour = 60 minutes, so 3 hours = 3 * 60 = 180 minutes.

Her total time was 3 hours and 28 minutes, so 180 + 28 = 208 minutes.

Divide her total time by total miles run:

208 minutes / 26 miles = 8 minutes per mile.
