Select the correct answer. A plane is traveling with an air velocity of 720 kilometers/hour due east. It experiences a headwind of 16kilometers/hour. Find the resultant velocity and direction of the plane with respect to the ground. A. 720.18kilometers/hour east B 704kilometers/hour east C 720.18kilometers/hoursoutheast D 736kilometers/hour east

To find the resultant velocity of the plane with respect to the ground, we need to consider both the air velocity and the headwind. The resultant velocity can be calculated by subtracting the headwind from the air velocity.<br /><br />Resultant velocity = Air velocity - Headwind<br />Resultant velocity = 720 km/h - 16 km/h<br />Resultant velocity = 704 km/h<br /><br />Therefore, the correct answer is B. $704kilometers/hour\quad east$.
