Forty-one 5th-grade and 43 6th-grade children were confronted with the task of determining which of two cars ran farther, faster, or for a longer amount of time solely based on the information provided about the relations on the other two dimensions. In each problem, the information as premise was presented in the form of two sentences and there were three other sentences as answer options. The participants took part in two kinds of task. In the qualitative task, the information as premise included no numerical values, while in the quantitative task, they were included. The main results were as follows : (a) The quantitative task was easier than the qualitative task. (b) The task performances were better in the 6th-graders than in the 5th-graders. (c) Judging about time based on both the proportional relation with distance and the inversely proportional relation with speed was most difficult. (d) The performances in the qualitative task seemed to predict considerably well the achievements in math "speed".
