Question 3

To conduct Sports Day activities, in your rectangular‑shaped school ground $ABCD$, lines have been drawn with chalk powder at a distance of $1\text{ m}$ each. $100$ flower pots have been placed at a distance of $1\text{ m}$ from each other along $AD$, as shown in Fig. 7.12.

Niharika runs $\dfrac{4}{5}$ of the distance $AD$ on the $2^{\text{nd}}$ line and posts a green flag.

Preet runs $\dfrac{1}{5}$ of the distance $AD$ on the $8^{\text{th}}$ line and posts a red flag.

What is the distance between both the flags?

If Rashmi has to post a blue flag exactly halfway between the line segment joining the two flags, where should she post her flag?
