Y = 1/3x
------------
y = - 5
- 5 = 1/3x
x = - 5 : ( 1/3 )
x = - 15
---------------
y = 1/6
1/6 = 1/3x
x = 1/6 : 1/3
x = 1/2
------------------
y = 0,2
0,2 = 1/3x
x = 1/5 : 1/3
x = 3/5

3 * 4 = 12 ( км )
Ответ 12 км
(1/5-1/4):(-1,6-3,3+5)=(0,2-0,25):0,1=-0,5
1.6 * 10^2=160
8*10^-1=0.8
160/0.8=200
Х=0,23*15/6,9=3,45/6,9=0,5.
