Question

if mount Everest is currently 8849m high and has an estimated growth rate of 5cm/year
what will be the hieght in 2025?
what would be the average height of mount Everest in 2025?
how long will it take mount Everest to reach 8850m?
what is the projected year for the mountain to reach 8850m in height?

Answer 1

To calculate the future height of Mount Everest and answer your questions, here are the steps:

1. **Current Height**: 8849 meters
2. **Growth Rate**: 5 cm/year, which is 0.05 meters/year.

### 1. Height in 2025
The current year referenced is 2023. To find out the height in 2025:

- Years until 2025 = 2025 - 2023 = 2 years
- Height increase = Growth Rate × Years = \(0.05 \text{ m/year} \times 2 \text{ years} = 0.1 \text{ m}\)

Now, add this to the current height:
- Future Height = Current Height + Height Increase
- Future Height = 8849 m + 0.1 m = 8849.1 m

### 2. Average Height in 2025
The average height of Mount Everest in 2025 would be the same as the height in 2025, which is 8849.1 meters.

### 3. Time to Reach 8850 m
To find how long it will take for Mount Everest to reach 8850 m from its current height of 8849 m:

- Height difference = 8850 m - 8849 m = 1 m
- Time = Height difference / Growth Rate = \(1 \text{ m} / 0.05 \text{ m/year} = 20 \text{ years}\)

### 4. Projected Year to Reach 8850 m
If it takes 20 years from 2023 to reach 8850 m:

- Year = 2023 + 20 years = 2043

### Summary
- Height of Mount Everest in 2025: **8849.1 m**
- Average height of Mount Everest in 2025: **8849.1 m**
- Time to reach 8850 m: **20 years**
- Projected year to reach 8850 m: **2043**
