Question

An aeroplane flies with speed 400 km/hr along east and
then with speed 300 km/hr along south for equal times.
What is the average (i) speed (ii) velocity of the plane?
If the plane moves back to the place of its start by the
shortest route, what is the net velocity of the plane?​

Answer 1

Answer:

Speed

There is more to motion than distance and displacement. Questions such as, “How long does a foot race take?” and “What was the runner’s speed?” cannot be answered without an understanding of other concepts. In this section we will look at time, speed, and velocity to expand our understanding of motion.

Answer 2

Answer:

average speed is 350km/hr because average speed=total distance/total time

and average velocity=u+v/2 therefore 250km/hr is the answer
