S= d/t
Answer:
62.2 mph East
Explanation:
Velocity is the distance moved per unit time with consideration to the direction of movement.
Velocity, v=d/t
Where d is distance and t is duration or time
Substituting 560 miles for distance and 9 hours for time then
V=560/9=62.222222222222 miles per hour
Rounded off to 1 decimal place
V=62.2 mph
The direction is East of New York
Therefore, conclusive velocity is 62.2 mph East
