There are two men. While the first covers 8 steps, the second covers 5 steps. The first covers a distance by 6 steps and the son covers the same distance by 6 steps. If the second person covers 60 m, how many meters will the father cover?
It is suggested that the father is the first man and the son is the second. Since "the first covers a distance by 6 steps and the son covers the same distance by 6 steps", their steps are of equal length, but father steps "faster". If the son covers 60 m, the father will cover m.

Statement (1) tells us that their steps have the same length.
Statement (2) tells us that the father walks as fast as his son.

Therefore, the father walked: . m.
