Question

Which graph could represent a car driving uphill at a constant speed?

Answer 1

Picture A will not work because although upward, it is NOT constant

Picture B is not going upward, so it's incorrect

Picture C is Constant but it's going downwards

Picture D is Constant and is going upwards, so it is correct
----------------------------------------------------------------------------------------------------
Picture D is your answer

Answer 2

The bottom left graph would correctly attribute to your question.

It is going at a constant increase, and if you looked at the graph, you would see that the distance from the top of the hill is decreasing. That is why the bottom left graph would be correct.

I hope this helps!
