Answer:
The average speed would be 279.167 meters per second.
Explanation:
Speed is the magnitude that expresses the variation in position of an object and as a function of time. In other words, speed is defined as the relationship established between the distance traveled and the time elapsed in the movement of a mobile.
Speed can be calculated using the following expression:
[tex]Speed=\frac{distance}{time}[/tex]
In this case:
Since the required unit of speed is meter per second, then you convert from km to meters for the case of distance, and from hours to seconds for the case of time. So:
Replacing in the definition of speed:
[tex]Speed=\frac{7,035,000 meters}{25,200 seconds}[/tex]
Solving:
[tex]Speed=279.167\frac{meters}{ seconds}[/tex]
Then, the average speed would be 279.167 meters per second.
