Answer 1
1
INCORRECT
The first graph says as the time goes by you are the same distance. So you must not be
moving. The second graph contradicts that by saying your speed is increasing. return to top
Answer 2
2
INCORRECT
The first graph says that as time goes by the distance is getting smaller. That goes
against what the second graph is saying. The second one says that as time goes buy the
speed is increasing. return to top
Answer 3
3
CORRECT
YES! As time goes buy the distance is increasing faster and faster. The second graph says
the same thing. As time goes buy the speed increases. return to top
Answer 4
4
INCORRECT
The first graph says as time goes buy the distance is getting less and less which goes
against the secong graph. The second one says that as time goes buy the speed is
increasing. return to top
What's this question really asking?
Can you find two graphs that discribe the same relationship? return to top
