Answer:
John ran the most. option (a) is true.
Explanation:
We need to compare the distances run by each person to determine who ran the most.
Here's how we can do it:
Express all the distances in the same unit:
Convert all distances to miles by multiplying each by 10^1:
Michael: 3.4 x 10^1 miles = 3.4 miles
Antwan: 3.1 x 10^1 miles = 3.1 miles
John: 3.6 x 10^1 miles = 3.6 miles
Compare the distances:
John ran 3.6 miles, which is more than Michael's 3.4 miles and Antwan's 3.1 miles.
Therefore, John ran the most.
Thus, option (a) is true.
