Answer:

Daniel is rollerblading at 15 miles per hour

Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15

Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15

The position of a particle on the x-axis at time t, t > 0, is s(t) = ln(t) with t measured in seconds and s(t) measured in fe

Mrrafil [7]

Answer:

C. The quotient of the natural logarithm of 2 and e.

Step-by-step explanation:

The position of a particle on the x-axis at time t, t > 0, is given by

$s(t) = \ln(t)$

with t is in seconds and s(t) is in feet.

The rate of change is,

= $\dfrac{f(b)-f(a)}{b-a}$

So rate of change of position or average velocity, for e ≤ t ≤ 2e will be,

$=\dfrac{\ln2e-\ln e}{2e-e}$

$=\dfrac{\ln2e-\ln e}{e}$

$=\dfrac{\ln\frac{2e}{e}}{e}$

$=\dfrac{\ln2}{e}$

Therefore, option C is the correct answer.
