We were told that the distance 
is directly proportional to the time 
.
We write this mathematically as,
We can now introduce our constant of variation and write the equation for the direct equation as;
where 
is the constant of variation or constant of proportionality.
We substitute 
and 
, in to the equation of variation to obtain the constant of proportionality.
That is;
This implies that,
This simplifies to give us,
Now our equation of proportion becomes,
When T=20
Writing this as a mixed number we obtain,
This can also be rewritten as
correct to one decimal places.
Therefore the care covers 
miles in 
minutes.

Answer:
(10,10)
Step-by-step explanation:
coordinates are (x,y)
x is horizontal(left and right), y is vertical (up and down)
going down 6 means subtracting 6 from the second number
lets reverse that to go up and add 6 back
4+6=10
so the original point was (10,10)
