## Question

###### Consider cach scenario: high-speed passenger train in Europe completes 900 km trip in hours. The train travels the first 600 km at an average speed that was 120 km/h faster than the last 300 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: 600 300 r+[20Identify all restrictions On the variable x in this context; (2 marks)Kailey is making earrings to sell at the local market: She spends S75 on supplies
