A discussion between elderly people was taking place in a park. They were talking about the environmental changes occurring day by day. One other group of grandchildren was also sitting beside them who came with their grandparents. After hearing their grandparent, the kids decided to fulfil the wish of greenery. They decided to plant more and more trees along the walking track which is $2 \mathrm{km}$ long. They draw the map in the notebook using the scale $1 \mathrm{mm} : 5 \mathrm{m}$. In the map, the distance between each tree is $5 \mathrm{mm}$.
