Although I think...
<span>the average velocity means, total distance over total time </span>
<span>so consider the formula speed=distance/time. </span>
<span>And break it down, the first part: </span>
<span>speed=40 km/h, time 2 h </span>
<span>distance= speed *times* time </span>
<span>= 40 * 2 </span>
<span>= 80 km </span>
<span>Then the second part: </span>
<span>speed=60 km/h, time 2 h </span>
<span>distance= speed *times* time </span>
<span>= 60 * 2 </span>
<span>= 120 km </span>
<span>Total distance / Total time = Average Velocity (keep in mind the basic formula speed=distance/time) </span>
<span>therefore, (120+80) km / 4 hrs </span>
<span>= 50 km/h </span>
<span>Hope I helped :)</span>

<h3>What happens in Huckleberry Finn Chapter 5?</h3>
During the next few months, Huck begins to adjust to his new surroundings and even makes some progress in school. One heel print depicts the devil as two crossed nails. Huck notices the mark right away and hurries to Judge Thatcher. That night, Huck pays a visit to Jim, who claims to be in possession of a large, supernatural hairball from an ox's belly. Jim listens to the hairball and informs Huck's father that he has two angels, one black and one white, one bad and one good.
