Final answer:
To find out how far the runner can go in 16 minutes at the same pace, we multiply 1/4th of 5 miles by 5 to get 1.25 miles.
Step-by-step explanation:
To solve this problem, we can use the concept of ratio. The runner completes 1/8th of a 5-mile race every 8 minutes, so in 16 minutes, the runner would complete 2/8th (or 1/4th) of the race. To find the distance, we multiply 1/4 by 5 miles:
Distance = 1/4 * 5 miles = 5/4 miles = 1.25 miles
Therefore, the runner can go 1.25 miles in 16 minutes.
