Answer:
C). 191 m/s
Explanation:
As we know that average speed is defined as the ratio of total distance moved by the plane and total time interval
So here we will have
[tex]speed = \frac{distance}{time}[/tex]
we know that
distance = 572000 m
times = 50 min
now we know that
[tex]v_{avg} = \frac{572000}{50 \times 60}[/tex]
[tex]v_{avg} = 191 m/s[/tex]
