Sagot :

Answer:

v = 5 m/s

Step-by-step explanation:

The variable d models drone's distance from the safe zone (in meters) t seconds after the drone started flying is :

d = -5t+4

We need to find the speed of the drone. Speed is the rate of change of position.

[tex]v=\dfrac{dd}{dt}\\\\=\dfrac{d}{dt}(-5t+4)\\\\v=-5\ m/s[/tex]

Hence, the speed of the drone is 5 m/s.
