11-99.

An object is moving in a straight line such that its distance traveled after

*t*minutes ismeters. Homework Help ✎ Find its average velocity over 0 ≤

*t*≤ 3.Find the acceleration of the object at

*t*= 2 minutes.

First, graph the equation and make sure the object does not change directions.

average velocity = (total distance)/(total time)

total distance = *s*(3) – *s*(0)

*s*(*t*) = ln(*t* + 1)
