A man started from home at 14:30 hours and drove to a village. When he arrived, the village clock displayed 15:15 hours. After staying for 25 minutes, he returned home by a different route. The route length was 1.25 times the first route, but he drove 2 times as fast. He reached home at 16:00 hours.
Compared to the clock at home, is the village clock running fast or slow, and by how many minutes?
