Final answer:
The total distance represents the distance the truck covers to stop, including both the distance it travels before hitting the brakes and the distance it takes to stop after hitting the brakes.
Step-by-step explanation:
To determine the total distance, we need to add the distance calculated in question 2 to the longest stopping distance in the class data table. This total distance represents the distance the truck covers to stop, including both the distance it travels before hitting the brakes and the distance it takes to stop after hitting the brakes.
