For this, we use the given info plus a bit of multiplying and subtraction
part 1)
we know that she's 25 y/m
so 5 minutes simply means 25 × 5
now we simply subtract this from 1000 (the original distance)
part 2)
the total time taken is even easier to find
all we have to do is divide 1000 by 25

Step-by-step explanation:
Given - f(t)=110(1.35)^{\frac{t}{40}}
To find - Write the function in the form f(t)=ae^{kt}. Round all coefficients
to four decimal places.
Proof -
Given that , the function is f(t)=110(1.35)^{\frac{t}{40}}
Now,
We can write it in the form of
By comparing with the form , we get
a = 110.0000
k = = 0.0250
