• Why do we integrate B(t) between the intervals of 0 to 10? Why can we not substitute 0 and 10 into the function of B in order to find the average velocity?

• That would only work if the function was perfectly linear.
• Why don't we integrate the function we found in part C between 0 to 10 to find average velocity? Why does it have to be B(t)?
