Clifton ran 6 miles in 39 minutes. At this rate, how much time Clifton takes to run one mile?
slavikrds [6]

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,

\frac{39 \ minutes}{6 \ miles}=6.5 \ minutes

              =(6+0.5) \ minutes -------(1)

To convert 0.5 minutes to seconds, let us multiply the value by 60.

Thus, we have,

0.5 \times 60= 30 \ seconds

Thus, substituting in equation (1), we have,

(6+0.5) \ minutes= 6 \ minutes \ and \ 30 \ seconds

Therefore, it takes 6 minutes and 30 seconds for Clifton to run one mile.

Hence, Option C is the correct answer.

Novosadov [1.4K]

Givens

Male  =      138,053,563

Female =   143,368,343

Total

The total equals 281 421 906

Percents

Male = (138,053,563 / 281 421 906) * 100 = 49.1%

Female = ( 143,368,343/ 281 421 906) * 100 =  50.94%

Rounded

Male =  49

Female = 51

Comment.

To find this %s you could just use the first 3 digits of everything.

Total = 138 + 143 = 281

% male = (138/281) = 49.1

% female = (143/281) * 100 = 50.88

These give you the same answers when rounding.
