Which graph best matches a person walking away at a constant speed
(Sorry the picture is a little cut off)

Answer 1

The second option

Step-by-step explanation:

Speed is defined at the rate at which distance changes with time. It is scalar quantity and it is expressed as shown below:

Speed =
`(distance)/(time)`

At constant speed the rate of change of distance with time is the same. On the second graph, this is noticeable. Both distance and time change at the same rate.
