Homework Statement
The velocity, in ft/sec, of a particle moving along the x-axis is given by the function v(t) = e^t + te^t. What is the average velocity of the particle from time t=0 to time t=3?
Answer: 20.086
Homework Equations
The Attempt at a Solution
Average velocity means the derivative formula, [s(t + Δt) - s(t)] / (Δt)
In other words, I get
[v(3) - v(0)] / (3-0)
[e3 - 3e3] / 3
And I got 26.447
[e3 - 3e3] / 3
And I got 26.447
However, the answer is 20.086.
What did I do wrong?
