[Verse 1] We’ve got a question we can try: Does waiting change the average? Why? Same route, same moving speed today— Only the pause will change along the way. [Chorus - call and response] What do we change? The time we wait! What do we measure? The whole-trip rate! Keep the route and moving speed the same; A fair comparison is our aim! [Verse 2] Start the clock when the trip begins; Keep it running till the finish comes in. Count the distance, count all the time— Divide them to find the average this time! [Bridge] Same distance, but a longer pause? More elapsed time—that’s the cause. The whole-trip average will be lower, Even when the moving part’s no slower! [Final Chorus - call and response] What do we change? The time we wait! What do we measure? The whole-trip rate! Keep the route and moving speed the same; A fair comparison is our aim!
