Answer:
v = 658.82 km/h
Explanation:
The distance between New York and London is [tex]5.6\times 10^3\ km[/tex]
Time taken from New York to London is 8.5 hours
We need to find the average speed of the plane.
Total distance covered divided by the total time taken is equal to the average speed of an object. So,
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{5.6\times 10^3\ km}{8.5\ h}\\\\v=658.82\ km/h[/tex]
So, the average speed of the plane is 658.82 km/h.
