The 1,600-meter race in the Olympics is very close to 1 mile long. How many kilometers is 1,600 meters?

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
