In a rectangular orchard, if the distance between each fruit tree is 5 meters and the distance between each row is 3 meters to plant fruit trees, 80 trees can be planted. If the distance between each fruit tree is changed to 4 meters, and the distance between each row is 2 meters, how many trees can be planted in total? (Hint: The area of the orchard remains the same.)
