Option C: Clifton takes 6 minutes and 30 seconds to run one mile.
Explanation:
Given that Clifton ran 6 miles in 39 minutes.
We need to determine the time it takes for Clifton to run one mile.
To determine the time that it takes for Clifton to run one mile, we shall divide 39 minutes by 6 miles.
Thus, we have,
[tex]\frac{39 \ minutes}{6 \ miles}=6.5 \ minutes[/tex]
[tex]=(6+0.5) \ minutes[/tex] -------(1)
To convert 0.5 minutes to seconds, let us multiply the value by 60.
Thus, we have,
[tex]0.5 \times 60= 30 \ seconds[/tex]
Thus, substituting in equation (1), we have,
[tex](6+0.5) \ minutes= 6 \ minutes \ and \ 30 \ seconds[/tex]
Therefore, it takes 6 minutes and 30 seconds for Clifton to run one mile.
Hence, Option C is the correct answer.
