Average speed is ALWAYS calculated as total distance / total time
<span>total distance is 100mi </span>
<span>total time is (50mi / 33) + (50mi / 80) </span>
<span>total time is = 1.52 + 0.625 = 2.145 </span>
<span>so average speed going to grandmothers house is 100mi / 2.145 hrs = 46.62 mph </span>
<span>on her return trip </span>
<span>x = V1 x t/2 + V2x t/2 </span>
<span>100 = 33t/2 + 80t/2 </span>
<span>100 = 113t/2 </span>
<span>t = 100x2/113 = 1.7699hrs </span>
<span>average speed = 100mi/1.7699hrs = 56.60mph</span>

Answer:
A Venn Diagram probably?
Step-by-step explanation:
A venn diagram would allow you to show the similarities and differences, because the inside of the circle would let you have the differences that only exist for that story, and then when the circle collides with another circle is where you can put the similarities to other circles.
There is even a venn diagram for 3 things, which would allow you to use the three stories.
