Final answer:
John ran the most with a distance of 36 miles.
Step-by-step explanation:
To determine who ran the most, we need to compare the distances ran by each runner.
Michael ran 3.4 x 101 miles, Antwan ran 3.1 x 101 miles, and John ran 3.6 x 101 miles.
To compare these numbers, we need to put them in standard form.
Michael: 3.4 x 101 = 34
Antwan: 3.1 x 101 = 31
John: 3.6 x 101 = 36
Therefore, John ran the most miles with a distance of 36 miles.
