Question

Can you answer this math homework? Please!

Answer 1

`\large \mathfrak{Solution : }`

Average speed :

• 
  `\boxed{ (distance \: \: covered)/(total \: \: time \: \: taken) }`

• 
  `(100)/(8)`

• 
  `12.5 \: \: m/s`

The horizontal (flat) line on a Distance - time graph shows that the body is at rest because the value of Distance (on y - axis ) is same for increasing time ( on x - axis ), it basically shows that the object is at the same position with the change in time.

therefore, correct option is :

• 
  `a. \: \: the \: \: object \: \: is \: \: not \: \: moving`
