alexander runs one mile in 8 minutes and walks it in 8 minutes slower. what is the ratio of his running speed to his walking speed, in simplest form?

answer: i'm not sure

step-by-step explanation:

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

i suppose it should be (y=2x-5)
