Identify all restrictions on the variable x in this context

A high-speed passenger train in Europe completes an 800 km trip in 3 hours. The train travels the first 600 km at an average speed that was 100 km/h faster than the last 200 km of the trip. If x represents the average speed of the train on the second part of the trip, then an equation to represent this situation is: (600/(x+100))+(200/x)=3. Identify all restrictions on the variable x in this context
