Final answer:
Geri took 8 minutes to run each mile in the marathon.
Step-by-step explanation:
To find out how many minutes it took Geri to run one mile, we need to convert her total time to minutes. Since 1 hour = 60 minutes, we can multiply 3 hours by 60 to get 180 minutes. Then, we add the 28 minutes to get a total of 208 minutes. Finally, we divide the total minutes by the number of miles she ran: 208 minutes ÷ 26 miles = 8 minutes per mile.
