Every minute, the man is climbing 3 meters and falling 2 meters back, he is essentially climbing 1 meter every minute.
Therefore, he would have climbed 57 meters in 57 minutes.
The remaining distance is 3 meters until the top of the mountain.
He will take one more minute to climb 3 minutes and reach the top.
Considering that he has reached the top of the mountain, he won't slip back down.
