The Gardiner dam located 100 km south of Saskatoon is largest earth filled dam in the world. Upon it's opening in 1967, engineers discovered that the pressure from lake deifenbaker had moved the clay based structure 200 cm downstream. Since then, then the dam has been moving at rate of 2 cm per year. Determine the distance the dam will have moved downstream by the year 2020?
Where did you get the 6 in the last part?
To determine the distance the dam will have moved downstream by the year 2020, we need to calculate the total distance moved from 1967 to 2020.
Total time = 2020 - 1967 = 53 years
Rate of movement = 2 cm per year
Total distance moved = Rate of movement * Total time
= 2 cm/year * 53 years
= 106 cm
Therefore, the Gardiner dam will have moved 106 cm downstream by the year 2020.
To determine the distance the dam will have moved downstream by the year 2020, we can use the formula:
Distance = Initial Distance + (Rate of Movement * Number of Years)
Given:
- Initial Distance = 200 cm
- Rate of Movement = 2 cm/year
- Number of Years = 2020 - 1967 = 53 years
Substituting these values into the formula:
Distance = 200 cm + (2 cm/year * 53 years)
Distance = 200 cm + 106 cm
Distance = 306 cm
Therefore, the dam will have moved 306 cm downstream by the year 2020.
Assuming that the dam had moved 200 cm by 2014 --
2014 - 1967 = 47 years
200 / 47 = 4.255 cm/year
(6 * 4.255) + 200 = ?
