Answer 2

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

$speed = \frac{distance}{time}$

we know that

distance = 572000 m

times = 50 min

now we know that

$v_{avg} = \frac{572000}{50 \times 60}$

$v_{avg} = 191 m/s$
