Race Placement Explained
This question involves understanding what a specific rank means in the context of a race.
The question states there are 40 runners in total, and Anu is placed 15th.
Being placed 15th means that Anu finished the race after 14 other runners had already finished, and she is the 15th person to cross the finish line.
The runners who are ahead of Anu are those who finished before her. These would be the runners ranked 1st, 2nd, 3rd, ..., all the way up to 14th.
Calculating Runners Ahead
To find the number of runners ahead of Anu, we simply subtract 1 from her rank.
The formula is:
Number of runners ahead = Anu's Rank - 1
Plugging in Anu's rank:
Number of runners ahead = $15 - 1$
Number of runners ahead = $14$
Therefore, there are 14 runners ahead of Anu in the race.
The total number of runners (40) is extra information and not needed to determine how many are ahead of Anu based on her specific rank.
