    Arnold is jogging west at 5 kph along a trail. Ivan is jogging east on the same trail at 3.75 kph.If they are 0.5 km apart, how long will it be until they meet?

    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!)
