Final answer:
To estimate travel time for 12 miles using a scatterplot, locate 12 miles on the x-axis, find where this value intersects the trend line, and then read the corresponding time from the y-axis. The exact time depends on the slope of the trend line, which cannot be calculated without the scatterplot or data.
Step-by-step explanation:
To estimate how many hours it will take to travel 12 miles, we need to analyze the scatterplot and use the trend line that represents the relationship between distance and travel time. First, we would plot the distance of 12 miles on the x-axis and then use the slope of the trend line to interpolate the corresponding time on the y-axis. However, without the actual scatterplot or the data that the scatterplot represents, we cannot provide a specific number of hours. If we had the scatterplot, we would follow these steps:
- Find 12 miles on the x-axis.
- Move vertically from this point until you meet the trend line.
- From the intersection point, move horizontally to the y-axis to find the corresponding time.
Since there could be variability in data points, determining the hours exactly may require further mathematical calculations based on the trend line equation, specifically the slope calculation, which is typically found by dividing the change in y by the change in x between two distinct points on the line.
