Somehow I feel there is some information missing in the question...? Explain your answer.
Surely if the journey is long enough they will be in step at least once with the left foot...What am I missing?
It is a matter of perspective. They will never start a left footstep at the same time, but they can complete a left footstep at the same time. Odd numbered steps will always be right, even steps will always be left. After the man takes 4 steps, the boy will have taken 6, and those would be left footsteps.
uuhh ok
