Answer 2

Concept:

The average speed is defined as the total distance traveled by an object in a particular time interval.

Given:

Tarun's average speed while driving from his home to the office, $S_1=60km/h$.

Tarun's average speed while driving from his office to home, $S_2=40km/h$.

Find:

The average velocity of Tarun.

Solution:

Tarun's speed from home to office, $S_1=60km/h$.

Tarun's speed from office to home, $S_2=40km/h$.

Let the distance from his home to his office be $x$.

So the time taken from both home to office and office to home are:

$T_1=\frac{x}{60},T_2=\frac{x}{40}$

Now, the required average speed = Total distance/Total time taken

So, Average velocity is,

$=\frac{x+x}{\frac{x}{40}+\frac{x}{60} }$

$=48km/h$

The average velocity is $48km/h$.
