# Average Speed

#### Evaluation After completing the tasks involved in this webquest, you should have a complete understanding of average speed and how to calculate average speed, distance and time.

Below you will find your roadtrip itinerary. Use your newly aquired knowledge to solve for the total time you spent driving in your car. You will need to understand how average speed, distance and time are all related in order to complete this task. Make sure you write all equations and work on a separate piece of paper that demonstrates how you arrived at your final solution.

Use the itinterary to discover how much time you will spend driving in your car, how many miles you will travel and what is the average speed you will be driving at.

Day One

San Diego to Los Angeles...116 miles with an average speed of 60 mph.

Los Angeles to Santa Barbara...95 miles with an average speed of 50 mph.

Day Two

Santa Barbara to Monterey...195 miles which took you 3.75 hours to drive.

Day Three

Monterey to San Francisco...112 miles which took you 3.25 hours to drive.

Day Four

Have some fun in San Francisco!

Day Five

San Francisco to Modesto...which took you 1.5 hours to drive at an average speed of 60 mph.

Modesto to Fresno...which took you 2.0 hours to drive at an average speed of 55 mph.

Day Six

Fresno to San Diego...318 miles at an average speed of 60 mph.

Remember to show your work and the equations you used to help you as you will be turning this assignment into your teacher. Write a paragraph to your parents presenting how much total time you and your friends will spend driving, what your average speed will be for the entire trip, and how many miles you expect to drive on your roadtrip?
