An aeroplane moving horizontally with a speed of $720 \, km/h$ drops a food packet while flying at a height of $396.9 \, m$. The time taken by the food packet to reach the ground and its horizontal range are (Take $g = 9.8 \, m/s^2$):
- A$3 \, s$ and $2000 \, m$
- B$5 \, s$ and $500 \, m$
- C$8 \, s$ and $1500 \, m$
- D$9 \, s$ and $1800 \, m$
