Answer:
Step-by-step explanation:
(7 , -1) = (x1 , y1)
(9 , -9) = (x2 , y2)
distance formula = 
=
=
=
=
=
The first point is on the 10 minute line in between 4 and 6 kilometer line
The second point is on the 15 minute in between the 10 and 12 kilometers line
The third point is on the 20 minute line and 18 kilometer line
1st add 7 to both sides : 3z = 21, 2nd divide both sides with 3: z = 7
-- To change a percent into a decimal, move
the decimal point two places this way <== .
33.3% = 0.333 .
-- To change a percent into a fraction, remember
that the symbol ' % ' means ' /100 ' .
33.3 % = 33.3/100 .
That fraction looks ugly, because it has a decimal in the numerator.
That's easy to fix. Multiply top and bottom by 10, and you have
333/1000 .
