Sarah wanted to know the velocity of an airplane traveling from houston to dallas. after recording the distance (in miles) and time (in hours) it took to travel to dallas, what other measurement does sarah need to determine the airplanes velocity? a) acceleration b) direction c) force d) inertia

Option B is the correct answer.

Explanation:

 Velocity of a body = Displacement of the body/Time taken

Displacement and velocity are a vector. Both have direction and magnitude.

Displacement is generally distance with direction.

If we divide distance with time taken we will get speed of the airplane. Speed with direction is called velocity. So we need distance between Houston and Dallas, time taken by plane to travel from Houston to Dallas and direction of displacement from Houston to Dallas.

So we need direction.

Option B is the correct answer.

the inner core.

good luck: )
