Calculate the average increase in world grain production per person per year from 1950 to 1984, given the following information:
- In 1950, the production was 247 kg per person.
- In 1984, the production was 342 kg per person.
Answer (2)
The student asked how to calculate the average increase in world grain production per person per year from 1950 to 1984. To find this, we use the information provided: 247 kg of grain per person in 1950 and 342 kg per person in 1984.
First, we find the total increase in grain production per person over the period by subtracting the initial value from the final value:
342 kg - 247 kg = 95 kg.
Next, we determine the number of years over which this increase occurred:
1984 - 1950 = 34 years.
We then divide the total increase by the number of years to find the average annual increase:
95 kg ÷ 34 years ≈ 2.79 kg per person per year.
Therefore, the average increase in grain production per person per year from 1950 to 1984 was approximately 2.79 kg.
The average increase in world grain production per person per year from 1950 to 1984 was approximately 2.79 kg. This was calculated by finding the total increase in production (95 kg) over the period of 34 years. Therefore, the average annual increase was calculated as 34 years 95 kg ≈ 2.79 kg per person per year .
