Let us consider the two vector which are u and v. The subtraction or addition of the two vectors will give the resultant of these two vectors.
The resultant will be in case of subtraction is,
And in the case of addition
And this resultant can be done by the help of vector law of addition by the parallelogram method or triangle law of addition.

Given:
Total distance = 1000 kilometer
Total time = 5 hours
To find:
Average speed = ?
Formula used:
=
Where = average speed
s = total distance
t = total time
Solution:
Average speed of the jet is given by,
=
Where = average speed
s = total distance
t = total time
=
= 200 km/ h
Thus, average speed of the jet is 200 km/h.
Hence, Option (A) is correct.
