To determine the velocity the she need to know the time it takes the airplane to move between two points.
What is the difference between speed and velocity?
Speed is a scalar quantity means it depends on magnitude value only and velocity is a vector quantity means with magnitute it also depends on the direction also.
Velocity is define as the distance travelled by any object in the given time interval and it is represented as:
v = dx/dt
Hence the time it takes the airplane to move between two points is required.
