Chapter 103 Waiting for the Tram

The three brothers, coming home from the theater, walked to the tram stop, ready to jump on it as soon as it came.However, the car never showed up.Brother's opinion is to wait. —Why wait here,—said the second child,—you might as well go on!Let's jump on it when the car catches up. We can already walk a distance while waiting, so we can get home earlier.

—If we go,— objected my brother,—then don't go forward, but go back, so that we can meet the oncoming traffic more quickly, and we can get home sooner.

None of the three brothers could convince others, so they had to go their own way: the eldest brother stayed at the station and waited for the bus, the second child walked forward along the direction of the train, and the younger brother walked back.Who among the three brothers will return home first?Who did it the smartest?

[Answer: My younger brother walked backwards for a while, saw an oncoming tram, and jumped on it.The car drove to the station where the elder brother was waiting for the bus, and the elder brother jumped up.After a while, the car caught up with the second brother and let him get in the car too.The three brothers were all sitting in the same car, and of course returned home at the same time.But the smartest one was the eldest brother, who stayed at the original station and waited comfortably, taking a shorter distance than the two younger brothers. ]
