Alejandro wrote an equation to fit the following scenario.

A person driving a pick-up truck and another person driving a motorcycle arrange to meet at a park. The pick-up truck driver took twice as long to arrive while driving at an average speed of 45 mph. The motorcyclist drove 55 mph and had a 23 miles less to drive.

Alejandro’s work:
t = number of hours for the pick-up truck driver to complete the trip
Equation: 55 (2 t) minus 23 = 45 (t)

Which statements identify Alejandro’s errors? Select the two correct answers.
He should have added the 23 to the motorcyclist’s distance instead of subtracting to balance the equation.
He should have written 45(2t) for the pick-up truck driver’s distance, since the he took twice as long.
He should have written 55(t) for the motorcyclist’s distance since t = number of hours for the pick-up truck driver to complete the trip.
He should have written 55 (one-half t) for the motorcyclist’s distance since it only took half the time as the pick-up truck driver.
He should have translated the scenario as motorcycle distance + pick-up truck distance = 23 since 23 is the distance mentioned.

Now that you’ve identified several points on the graph, it’s time to create the graph this spreadsheet. Plot the time (in hours) along the x-axis, and the distance (in miles) along the y-axis. Follow these steps to create the graph:

Open a new worksheet in the spreadsheet.
In cells A1 through A7, enter the number of hours for each data point. Be sure to start with 0. The order of your data points is important.
In cells B1 through B7, enter the number of miles for each data point. Be sure to start with 0. Again, the order of your data points is important.
Click and drag to highlight cells A1 through A7 and B1 through B7 into which you entered data values in steps 2 and 3.
From the main menu, click Insert. In the drop-down menu for charts, select Scatter with Straight Lines and Markers.
Your graph should now appear in a new window. Take a screen capture of the graph, and insert the image into the response area using the Insert Image button.

Which of the following correctly uses absolute value to show the distance between −50 and 12?

|−50 − 12| = |−62| = −62 units

|−50 + 12| = |−38| = 38 units

|−50 + 12| = |−38| = −38 units

|−50 − 12| = |−62| = 62 units
