On a speed time graph, the distance can be calculated by working out the area underneath the line. To work out the distance travelled between t=0 and t=10 you would need to find these two values and then work out the area on the graph of the shape bound by the line of the particle, the x axis, t=0 and t=10. The average speed of the particle is the distance (calculated above) divided by 10.
Speed = 10/7 m/s
10 meters per second 100/10=10
We always calculate distance by multipying the speed by time. ex: I travelled in 10 min at the speed of 60km/h , so the distance equals to 60 times 10 which equals to 600 km....
To determine the value of 10 to the power of -8, we can take the reciprocal of 10 raised to the power of 8. Since 10 to the power of 8 is 100,000,000, the value of 10 to the power of -8 is 1 divided by 100,000,000, which equals 0.00000001.
