Questions 1 & 2:

You and Benji are driving down the highway in Benji's 1967 Volkswagen Beetle, and all of a sudden the speedometer stops working. Since he already has several speeding tickets, it is imperative not to get another ticket or he will lose his driver's license. You are wearing a watch with a stopwatch feature and you can see the highway mile markers along the highway.

1. How would you determine the car's average speed?


2. What is your evidence for your answer in question 1? (How do you know?)
