问题     Miss Rogers taught physics (物理) in a New York school. Last month she was teaching to one of her classes about sound (声音). "Now, I have a brother in Los Angeles (洛杉矶). If I was calling him on the phone, and at the same time you were 75 meters away listening to me on the other side of the street, which of you would hear me earlier, you or my brother? And why?"
    John answered, "Your brother, Miss Rogers, because electricity (电流) travels faster than sound waves." "That’s very good," Miss Rogers said.
    "I disagree," said Mary. "Your brother would hear you earlier, because when it’s eleven o’clock here, it’s eight o’clock in Los Angeles."
Miss Rogers was telling her students about sound.
