Question

Help please ! 15 points

Answer 1

The labeled point means the Amelia biked 1.5 30 miles in 1.5 hours. 
This means that in 1 hour, Amelia biked 20 miles.
Her distance changed at a unit rate of 20 miles per hour, so that was her speed.

Answer 2

For your first question, take a look at the labeled coordinates (1.5, 30) on the graph. What do the x and y coordinates here represent? Take a look at the axis labels if you're having trouble figuring it out, and use that information to select from each of the drop-downs.

For the second part, take a look at the axis labeled "Time (hours)" and find the notch labeled "1". Notice where its gridline hits that red line, and notice what the corresponding notch is on the axis labeled "Distance (miles)". That notch will give you your distance for the question.

The third answer should have the same result as the second; by finding the distance she traveled in one hour, you've already found her "unit rate" in miles per hour.
