MCQ
Data was collected on a student’s typing rate and graph was drawn as shown below. Approximately how many words had this student typed in $30$ seconds$?$
- A$20$
- B$24$
- ✓$28$
- D$34$
✓
Answer
Correct option: C.
$28$
Observing the graph, we see that the graph intersects the line $x = 30$ just below the point $(30, 30),$ which is the intersection of the lines* $= 30$ and $y- 30.$
Since, the $X-$axis represents the time (in seconds) and the $Y-$axis represents the number of words typed, therefore we conclude that the students had typed approximately $28$ words In $30s.$
