If you want the distance from the starting point, you can use the Pythagorean Theorem. You can also use your calculator's rectangular --> polar conversion; this will give you not only the distance, but also the angle.

Indeed it is.
The resultant velocity of a plane is 75 km/hr.
3 blocks east
Total of 6m north and 1m west. Using Pythagoras that's sqrt(36+4) miles in total at an angle whose tangent is 1/6, west of north.
100 km and 75 km are displacements, NOT velocities. The resultant displacement is 25 km north,
find the resultant of the following displacement a=20km 30south of east
The resultant is 2 km South.
It's 17.0m North. (20N - 3S)
The resultant is 220 North.
Distance 2+3=5 displacement 2
The car has traveled a total distance of 18 miles (10 miles south + 8 miles north), but its displacement is 2 miles south. Displacement is the shortest distance between the starting and ending points, regardless of the actual path taken.
subtract 1 from 2
Draw a vector from his starting point to his ending point.
The displacement is a shortest distance. Here, the displacement will be 1 km. It will be in the North direction.

Velocity of a moving body is its rate of DISPLACEMENT with respect to time. But speed is distance traveled per unit time. The difference between speed and velocity is that velocity has a direction. 30mph is a speed. 30mph due north is a velocity. Well not really because 'north' is arbitrary but you get the idea. Displacement is both a distance and direction. 30 miles is a distance. 30 miles to the north is a displacement. A two part quantity like velocity or displacement is called a 'vector quantity'. A one part quantity (speed, distance etc) is called a 'scalar quantity'.
