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:
Step-by-step explanation:
y - 3 = 2(x + 2)
y - 3 = 2x + 4
y = 2x + 7
so to find angle one you just subtract the other angles from 180°
180°-33°-92°=55°
angle 2 is going to be equal to the adjacent angle every time so it's equal to 92°
angle 3 you just subtract everything from 360°
360°-90°-115°-92°= 63°
