In the given figure, find the total distance travelled.
"

Given :

The figure is given as speed - time graph.

To find :

We have to find the total distance travelled in the figure.

Solution :  

We know that,

The area under the speed-time graph is the distance the particle travels.

The area of the given figure $= \frac{1}{2} \times 20 \times 100 + (100-20)\times100 + \frac{1}{2} \times (140-100)\times100$

                                                    $= 10\times100+80\times100+40\times50$

                                                   $= 1000+8000+2000$

                   Distance travelled  = 11000 m² .  

Total distance travelled is 11000 m²
