The truck that starts moving first is faster. The truck that takes less time is faster. The truck that has bigger tires is faster. The truck that takes more time is faster.
I gave my students this multiple choice question: A class measures the time it takes for two different trucks to drive across the parking lot. How can they tell which truck is faster?

Only one answer is correct among these 4 choices:
- The truck that starts moving first is faster.
- The truck that takes less time is faster.
- The truck that has bigger tires is faster.
- The truck that takes more time is faster.

Could you tell me which one is correct?

The truck that takes less time is faster.
