Question

An average speed for a time interval is 40 km/hr. Which is the correct time interval?

Answer 1

The correct time interval is (2,20) to (4,80).

What is the average velocity?

The average velocity is defined as the velocity or speed of the body throughout the period of motion under consideration. This will always span the entire journey. Recall that velocity is the ratio of distance covered to time taken. The average velocity spans the entire journey and differs from the instantaneous velocity which occurs at a particular point along the journey.

Now we know that the average distance is obtained as the sum of the initial and final velocity multiplied by time and divided by two. Bear in mind that the question already contains the information that we have been told that the average velocity here is 40 km/hr. We can clearly see from the forgoing that the correct time interval is (2,20) to (4,80).
