Martin can run a kilometer in 7 minutes. If he keeps at this pace how many minutes will it take him to run a 5k race?

35 minutes

Step-by-step explanation:

Martin can run a kilometer in 7 minutes. If he keeps at this pace how many minutes will it take him to run a 5k race?

To solve this, we simply need to use proportion.

Let x represent the number of minutes that will take Martin to run a 5 kilometer race

1  kilometer = 7 minutes

5 kilometer = x

cross-multiply

1 × x  =  7 × 5

x = 35 minutes

Therefore, it will take Martin 35 minutes to run a 5 kilometer race.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
