Chapter 142 Who Wins Between Brothers
The brothers compete in the 100-meter sprint.As a result, the elder brother won by 3 meters. In other words, when the elder brother reached the finish line, the younger brother only ran 97 meters.The brothers decided to have another match.This time, my brother retreated 3 meters from the starting line and started running.Assuming that the speed of the two remains the same in the second race, who wins the second race?
[Answer: One might think that the result of the second game was a draw, but this answer is wrong.Because from the first race, it can be seen that the time required for the elder brother to run 100 meters is the same as the time required for the younger brother to run 97 meters.

Therefore, in the second race, the elder brother and the younger brother reached the AB line at the same time, and in the remaining same distance of 3 meters, because of the faster speed of the elder brother, of course he reached the finish line first. ]
