Using the Definition of average speed, we have:

$\Delta v= \frac{\Delta S}{\Delta t} \\ \Delta v= \frac{(4+6+4+6)}{12-9} \\ \Delta v= \frac{20}{3} \\ \boxed {\Delta v=6,7 km/h}$

Obs: approximate results

Letter D

If you notice any mistake in English, please let me know, because I'm not native.

PLZZZZZZZZZZZZZZZ HELPPPPPPPPPPPPP Which table represents a linear function?

kodGreya [7K]

Answer:The first one and the thrid one

Step-by-step explanation:

The second one isn't a linear one because number 5 represents 3,1... and that number is down the y's line. That means it has to go down again but without decreasing, stopping the function to become a linear one and becoming a non constant one.

I hope I'm being helpful...
