An annual sports day of a school, in the rectangular play-ground ABCD, lines have been drawn with lime powder at a distance of 1 m   each. 100   plastic cones have been placed at a distance of 1 m   each along AD. Niharika runs 1 20   th the distance AD on the 2nd line and posts a red flag. Preet runs 1 25  th the distance AD on the 8th line and posts a yellow flag. What is the difference in distance between the two flags?

### Solution:

Given that,   plastic cones have been placed at a distance of  each along AD.
We shall find the difference in size of two flags.
Lines have been drawn with lime powder at a distance of 1 m each.
plastic cones have been placed at a distance of  m each along Niharika runs   the distance AD on the   line and posts a red flag.
Preet runs   the distance AD on the 8th line and posts a yellow flag.

The distance formula between two points   is given by,

Here,

The distance between the points (2, 5) and (8, 4) is given by,

Distance between Niharika's flag and Preet's flag is  .
Hence, option 2) is correct.
