So the first thing that you might want to think about is well maybe distance is just the integral of the velocity function. We see that multiple times. If you want to find the change in a quantity, you just say the starting time and the ending time, and then you integrate the rate function. So wouldn't it just be that? Now we have to be very, very careful. If the question was what is the displacement for the particle between time equals two and times equals six, this would have been the correct answer. So this would be displacement, displacement from t equals two to t is equal to six.
