Explanation:

In a 50 - meter straight - line race, runners start from one point and move to another. As they move, their position in space changes from the starting point to the finishing point. Since it's a straight - line race, they don't change their direction. And their weight remains the same during the short - distance race.

Answer:

They will change their position.
