Calculating the ratio of the total distance travelled by the body to the time taken to cover that distance obtains the average speed.

\text{ Average speed } = \frac{\text{Total distance}}{\text{ Total time }}

        or

v_{avg} = \frac{d}{t}

Step 1: Finding the average speed

Speed is a scalar quantity. The speed is dependent only on the magnitude not on the direction

Given that

The Magan's distance walked to the left d = 1300 m

Time needed to walk t = 460 sec

Average speed   v_{avg} = \frac{d}{t}

v_{avg} = \frac{1300 m}{460 s}

v_{avg} = 2.82

Therefore, Average speed of Magan v_{avg} = 2.82 m/s
