Distance-Time Graph Analysis

The video tutorial explains how to graph a family's journey from Los Angeles to San Francisco. Initially, the family travels at 60 MPH, and the graph is plotted with time on the x-axis and distance on the y-axis. In the last hour, the speed increases to 80 MPH, resulting in a steeper slope on the graph. The tutorial demonstrates how to calculate and represent these changes visually.

What is the initial speed of the family driving from Los Angeles to San Francisco?

• 70 MPH

• 80 MPH

• 60 MPH

• 50 MPH

On a graph, which axis is typically used to represent time?

• X-axis

• Z-axis

• W-axis

• Y-axis

What is the starting point of the graph in terms of distance and time?

• 60 miles, 1 hour

• 120 miles, 2 hours

• 180 miles, 3 hours

• 0 miles, 0 hours

What does the y-axis represent in the graph?

• Time

• Acceleration

• Distance

• Speed

What unit is used to mark increments on the graph in this scenario?

• 90 miles

• 60 miles

• 120 miles

• 30 miles

After 2 hours of travel at 60 MPH, how far has the family traveled?

• 60 miles

• 120 miles

• 180 miles

• 240 miles

What is the total distance covered after 3 hours at 60 MPH?

• 120 miles

• 240 miles

• 180 miles

• 300 miles

How does the graph look during the first 3 hours of travel?

• Vertical line

• Horizontal line

• Curved line

• Straight line

What happens to the speed of the family in the last hour of the journey?

• It decreases to 50 MPH

• It remains at 60 MPH

• It increases to 80 MPH

• It decreases to 40 MPH

If the family had continued at 60 MPH for the last hour, what would the total distance be after 4 hours?

• 240 miles

• 300 miles

• 360 miles

• 420 miles
