Answer:

Nicko: So guys, i'm doing some crazy things with my test today, so the energy wasn't destroyed

Friends: Shut up lose-

Nicko: After doing calculations we realize the vehicle did not travel nearly as far as our thought it would when it used the gallon of gasoline.

Teacher: What's your opinion about that Nicko?
