Question

Miss Evans taught physics in a London school. Last month she was explaining to her class about sound, and she decided to test them to see how successful she had been in her work. She said to them, Now, I have a sister in Washington. If I was calling her on the telephone, and at the same time you were 20 meters away and listened to me from the other side of the street, who could hear what I said earlier, my sister or you? And why?
The cleverest boy at once answered, “Your sister, Miss Evans, because electricity (電)travels faster than sound waves(波).” That’s very good, Miss Evans answered, but then one of the girls put up her hand, and Miss Evans said, Yes, Betty?
“I don’t think so. Betty said, Your sister would hear you earlier because when it’s eleven o’clock here, it’s only six o’clock in Washington.”
