LINE ON 1 AND GOES TO THE MIDDLE OF 20 AND 25

Respuesta :

transitionstate

Answer: 3 m/s


Step-by-step explanation:

1) the instantaneous speed is the slop at t = 6 secs

2) since its a straight line, the slop of the line is the speed and its constant.

the slope is approximately 3 m/s.

                   t = 5    

So the formula for speed is

     speed = distance/time

              S = 15/5

              S = 3 m/s
