Protecting endangered species is essential to maintaining biodiversity and a healthy environment. One important way to help is by protecting their natural habitats through the creation of national parks and nature reserves. People can also reduce pollution and avoid using products made from endangered animals. Supporting laws that ban illegal hunting and trading of wildlife is another key step. Educating others about the importance of wildlife conservation can raise awareness and inspire action. Additionally, participating in tree planting and conservation programs helps restore ecosystems. By working together and making small, conscious choices in our daily lives, we can contribute to saving endangered species and ensuring a balanced, thriving planet for future generations.

Gọi vận tốc của bạn Hoa lúc đi là $x$ (km/h; $x>0$).

Thời gian bạn Hoa đi từ nhà đến địa điểm A là 24xx24​ (giờ).

Thời gian bạn Hoa đi một nửa quãng đường lúc về là 12xx12​ (giờ).

Vận tốc của bạn Hoa đi một nửa quãng đường còn lại lúc về là $x+4$ (km/h).

Thời gian bạn Hoa đi nửa quãng đường còn lại lúc về nhà là 12x+4x+412​ (giờ).

Do thời gian về ít hơn thời gian đi là $15$ phút $($đổi bằng 1441​ h$)$ nên ta có phương trình:

24x−12x−12x+4=14x24​−x12​−x+412​=41​

12x−12x+4=14x12​−x+412​=41​

x2+4x−192=0x2+4x−192=0

$x=12$ hoặc $x=-16$

Ta thấy $x=-16$ không thỏa mãn.

Vậy vận tốc của bạn Hoa lúc đi là $12$ km/h.
