The temperature at the surface is +24 ° С, and at a depth – +34 ° С. Determine the depth of the shaft.

+34 – 24 = 10 ° C. For 100 m, the temperature will rise by 3 ° С, and the increase by 10 ° С will be at (10: 3 = 3; 100 x 3 = 300) the depth of the mine is about 300 m.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
