You drive from Albuquerque, NM, to Rock Springs, WY, at an average
speed of 55 miles per hour. Your route is along Interstate 25 to
Cheyenne, WY, then Interstate 80 to Rock Springs.
A. Use an atlas or road map to calculate the number of miles you
drive and the total driving time (to the nearest half hour) in
Problem A above.
1. Write a brief description of the problem-solving process,
including steps, calculations, and tools used. Use actual road
distances in miles.
CONSTRUCT PROBLEM B USING THESE ELEMENTS
• Calculate travel time. Account for layovers.
• Travel by air from Memphis, TN, to Las Vegas, NV, with stops in
Oklahoma City, OK, and El Paso, TX, en route.
• Average aircraft groundspeed is 380 km/hour from Memphis to
Oklahoma City and 310 km/hour from Oklahoma City to Las Vegas.
B. Construct a problem using the information from Problem B above.
Assume that students will have a map of the United States that
shows cities and a distance scale in kilometers. Require use of
straight-line distance in kilometers for each leg of the trip.
1. Write a brief description of the process you used to construct the problem.
2. Write the steps you expect students to follow. Remember to include the
calculations and the answers to each step.
3. Provide a scoring key with directions for its use and application. Include the
answer ranges in the scoring key.
