There are 60 equally spaced trees around a circular lake. Khang runs exactly one lap in 8 minutes, then walks exactly one lap in 25 minutes. The number of metres he runs per minute, the number he walks per minute, and the distance in metres between consecutive trees are all natural numbers. The circumference of the lake is greater than 1500 m and less than 2000 m. How many metres apart are consecutive trees?
