The fastest airplane is the lockheed sr-71. if an sr-71 flies 15.0 km west in 15.3 s, what is its average velocity in kilometers per hour?

3529 km/h west

Explanation:

The average velocity is given by:

where

d is the displacement

t is the time taken

For the plane in this problem, we have:

Therefore, substituting into the formula,

and the direction is the same as the displacement (west).
