A quantitative comparison question.
Quantity A is "the fraction of the total distance x that is covered by Jane."
Quantity B is "(2/3)*x".
Quantity A is a constant (2/3), that is, Jane always covers two thirds of the distance, regardless of how large the distance is.
Quantity B is not a constant. If x is .5, than Quantity B is smaller. If x>1, the quantity B is larger.
By this reasoning the answer is D. The book says it is C.
Where am I going wrong in my reasoning?
Thanks!
