Question

Please help with 14 & 15 ! ( I will mark you brainliest )

Answer 1

The speed is the slope of the distance versus time graph.

To do Q15 first, the greatest speed is the steepest slope, line A.

Two points on A are (2,10) and (0,0) so a slope, i.e. a speed of 10/2=5 meters per second

In detail, the slope is rise over run:

$\textrm{slope}= \dfrac{\textrm{change in y}}{\textrm{change in x}}=\dfrac{10-0}{2-0} =5$

Q14 Answer: 5
