Answer:

Step-by-step explanation:
We are given the first derivative of
and the value of
.
To go from the first derivative to the original function, we integrate.
Therefore:

To integrate, we add 1 to the power and divide by the new power:

Because we have an indefinite integral, we have to add the constant,
, to the end.
So: 
We know
so we can find the constant
.


Therefore 
So18 is to 2 and54 is to 6
18:2 and 54:6
18/2 and 54/6
simplify
9/1 and 9/1
she is running at the same rate
so we need to do
t times something=k
its eems that she divided the time by 9
so
1/9t=k
the equation is 1/9t=k
