    They will never meet, as they are running away from each other.

    They WILL meet if they are initially facing each other!

    If Arnold moves at 5 kph, after t hours, How many km will he have gone? If Ivan moves at 3.75 kph, after t hours, how many km will he have gone? For what t will the total distance they go be 0.5 km?

    I think CompuChip was being facetious in his/her post.

    Later on ... I said to myself ...even if they were not facing each other, they would ... eventually meet (after going round the Earth!)
