What do you think the answer is?

Tonycoolkid21:

B

carmelle:

Well, your wrong because if we look closely the table is correct, For example, 1 hour is equal to 55 miles

carmelle:

and so on...

carmelle:

Therefore B can be eliminated. Any other guesses?

Tonycoolkid21:

D

carmelle:

Though the graph is really small, it seems pretty accurate. When you look at the graph, 1 hour seems to cross 55 miles. Therefore, D can be eliminated. We are now left with A and C. What do you think it is?

Tonycoolkid21:

carmelle:

No, that's not right either. The answer for this question would be c. Here's why: The equation used for A; d = 55t, can be used to prove C is wrong Lets substitute 3 with t d = 55(3) So, we should do 55 x 3 What do we get when we do that?

Tonycoolkid21:

yes B

carmelle:

Well, when we do 55 x 3 we get 165 not 160. That proves that C is the correct answer. Hope that help!! The answer to your question is C.
