A deer escapes from a leopard and runs away in straight line with constant velocity. The leopard starts chasing the deer, when the deer has ran a distance 48m. The leopard starts with initial speed 30 m/s but due to fatigue it has to reduce its speed and it does so by reducing speed in equal steps of 5m/s after every 2s interval. The minimum speed with which the deer must run to escape away from the leopard is 3n (m/s). Find n = ?
