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.

The two lines, P and Q, are graphed below: Line P is drawn by joining ordered pairs negative 8,15 and 6, negative 12. Line Q is

andreyandreev [35.5K]

Solution:

Keep in mind ,

Equation of line joining two points (a,b) and (p,q) is given by :

$\frac{q-b}{p-a}=\frac{y-b}{x-a}$

Equation of line P which is obtained by joining (- 8,15) and (6, - 12) is given by:

$\frac{y-15}{x+8}=\frac{-12-15}{6+8}\\\\ 14(y-15)=-27(x+8)\\\\ 14 y -210= -27 x - 216\\\\ 27 x+14 y+6=0$

Equation of line Q which is obtained by joining (4,16) and (-9, 10) is given by:

$\frac{y-16}{x-4}=\frac{16-10}{4+9}\\\\ 13(y-16)=6(x-4)\\\\ 13 y -208= 6 x - 24\\\\ 6 x-13 y+184=0$

Equation of line P and Q are

27 x+14 y+6=0-------(1)× 2

6 x-13 y+184=0-------(2)× 9

54 x + 2 8 y+12=0---(1)

54 x -117 y +1656=0----(2)

(1) - (2)

145 y= 1644

y=11.33,

27 x+14 y+6=0-------(1)×13

6 x-13 y+184=0-------(1)×14

351 x + 182 y + 78=0-----(1)

84 x - 182 y +2576=0----(2)

(1) + (2)

435 x + 2654=0

x = - 6.11

So, solution set is (-6.11, 11.33)

Option (C) is true. (−2, 4), because this point makes both the equations incorrect.
