A and B take part in 100 meters race, where A beats Bby 10 meters. To favour B, A starts 10 meters behind the starting line in a second 100 meters race, running at their earlier speeds.
Which one among the following is true in view of the second race?

{'meters race': [0, 0, 0, 1], 'second race': [0, 0, 0, 1], 'meters': [0, 1, 0, 2], 'earlier speeds': [0, 0, 0, 1], 'meter': [0, 0, 0, 2], 'starting line': [0, 0, 0, 1], 'line': [4, 1, 3, 4], 'beats': [0, 0, 0, 1]}

In the first race, A beats B by 10 meters. In the second race, A starts 10 meters behind B. This means that A essentially starts at the same point where B started in the first race.

Since A and B are running at the same speeds in both races, we can conclude that A will cover the same distance in the second race as B did in the first race.

Therefore, in the second race, A will cover the initial 10 meters and then cover the same distance as B did in the first race. As a result, A will end up covering a total of 10 meters more than B in the second race.

Hence, the correct option is 4 - A beats B by 1 meter in the second race.
