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.
She has been with her book club for 49 months.
Step-by-step explanation:
Books read = 12 books
