Answer:

[tex]\displaystyle \bar v=13.33\ m/s[/tex]

Explanation:

Average Speed

The speed of an object is the rate of change of its distance. When an object travels at different speeds over time, the average speed is usually calculated to represent the whole travel.

The average speed is the total distance (d) traveled by the object divided by the elapsed time to cover that distance (t):

[tex]\displaystyle \bar v=\frac{d}{t}[/tex]

The airplane covers a distance of d=1200 m in t=90 s. The average speed is:

[tex]\displaystyle \bar v=\frac{1200}{90}[/tex]

[tex]\boxed{\displaystyle \bar v=13.33\ m/s}[/tex]
