Answer:
2.25 it is the answer
Step-by-step explanation:
24 / 8 = 3
she eats 1 every 3 minutes
so
33 / 3 = 11
ur right.
It looks like the ODE is
with the initial condition of .
Rewrite the right side in terms of the unit step function,
In this case, we have
The Laplace transform of the step function is easy to compute:
So, taking the Laplace transform of both sides of the ODE, we get
Solve for :
We can split the first term into partial fractions:
If , then .
If , then .
Take the inverse transform of both sides, recalling that
where is the Laplace transform of the function . We have
We then end up with
Answer:
We can see from the table that 1 km is exactly half way between 2 and 3 laps. So it will take 2.5 laps to run 1 km. So it takes Angel 5 minutes to run 1 km.
