Xiaohong and Xiaoli used the temperature difference to measure the height of the mountain peak. Xiaohong measured the temperature at the mountain peak was 1.25 degrees, and Xiaoli measured the temperature at the foot of the mountain at 6.85 degrees. It is known that every 100 meters in height in this area will reduce the climate by about 0.8 What is the approximate height of this mountain in meters?
