Final answer:
Carson has run a greater distance and is 0.83 miles ahead of Nell.
Step-by-step explanation:
Carson is running a race that is 14.7 miles, and he has 3.27 miles left to go. Nell is running a race that is 12 miles and has 1.4 miles left to go. To compare who has run a greater distance, we can subtract the distance left from the total distance for each runner.
Carson: 14.7 miles - 3.27 miles = 11.43 miles
Nell: 12 miles - 1.4 miles = 10.6 miles
Carson has run a greater distance with 11.43 miles, and he has run 0.83 miles farther than Nell.
