Li Wei rides a motorcycle from home to the railway station. If he travels 30 kilometers per hour, he will be 15 minutes earlier than the train. If he travels 18 kilometers per hour, he will be 15 minutes later than the train's departure time. If Li Wei plans to arrive at the railway station 10 minutes before the train leaves, what's the speed of his motorcycle at this time?

Let the departure time of the train be x hours. From the meaning of the question: 30 (x-1560) = 18 (x + 1560), the solution is x = 1. Let Li Wei's cycling speed be y kilometers per hour, y = 30 × (1 − 1560) 1 − 1060 = 27. Therefore, Li Wei's cycling speed is 27 kilometers per hour
