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>
In the question "Athena priced each of her art pieces at the same price and displayed them for sale in two different art shows. She made $495.80 from the first art show and $371.85 from the second show. If Athena sold 7 pieces of art, what price did each piece sell for?"
To get the price that each piece of art sells for:
Total sales made from selling 7 pieces of art = $495.80 + $371.85 = $867.65
The price for each piece of art = $867.65 / 7 = $123.95
Thus each piece of art sells for $123.95<span> and hence the correct answer.</span>
So the general form followed most of the time is y=mx+b. The m represents the slope, so in this case the slope is 5.
