John’s house is 12 miles away from school. He is two-thirds of the way home. How many miles has he walked? A. 8 B. 16 C. 18 D. 2

Oksi-84 [34.3K]

This question is funny because the total he has to walk from school back home is 12 MILES. The question tries to confuse you by using the term “two-thirds”. Here is my point: He only had to walk a total of twelve miles. Why would the answer be 16, 18, and 24 miles when he only has to walk 12??? This is just common sense and I wouldn’t overthink the question. I hope I helped! Glad I caught this. Have a great night.

Tom's age is 5 more than twice Dic's age.

kvasek [131]

If we break the answer down, we can solve this pretty easily.
We can represent Dic's age with x.
Tom's age is 5 MORE (+5) than TWICE (2x) Dic's age (x)
Therefore, our answer is 5+2x (Five more than twice Dic's age)

The correct answer is C: 5+2x
