Explanation:

To find the average velocity of the particle over the interval [1, e], we need to calculate the net displacement divided by the time interval.

Given the position function x(t) = ln(t), let's find the displacement by evaluating x(e) and x(1):

x(e) = ln(e) = 1

x(1) = ln(1) = 0

So, the net displacement is 1 - 0 = 1.

The time interval is e - 1.

Therefore, the average velocity is:

average velocity = (net displacement) / (time interval)

average velocity = 1 / (e - 1)

The correct answer is B. 1/(e - 1).
