Question

Look at the graph below. It shows Angela's journey as she walks to the end of the road and back. Calculate her speed over section 1 of the journey.

Answer 1

Answer:.0.5m/s

Explanation: She originally walks 20 m per 40 seconds which also means she walks 10m per 20 seconds then 5m per 10 seconds then divide it by five and you get 1m per 2 seconds and just half it to find the answer. Hope it helps

Answer 2

The speed of Angela in section 1 of the graph is 0.5 m/s.

• The most crucial scientific notion is measurement. Base or physical fundamental units are used to quantify a wide range of quantifiable quantities. One such measurable metric is speed, which calculates the ratio between the distance an object travels and the time needed to cover that distance.
• The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Here, according to the given information, we are given that,

We need to find the speed of Angela in the section 1 of her journey.

Now, the distance travelled in the section 1 of her journey is 20 m.

Also, the time in which the first section is covered is 40 seconds.

Then, we know that,

Speed is distance per unit time.

That means,

Speed = $\frac{20}{40} = 0.5 m/s$

Hence, the speed of Angela in section 1 of the graph is 0.5 m/s.
