Calculate the average rate of change in corn yield from 1964 to 2008 (Round to the nearest whole number.)

In 1964 2.6 bales per hectare while in 2008, 380 bushels per hectare.

Explanation:

in 1964, the average corn yield was 2.6 bales per hectare which is equals to 570 kg per hectare while in 2008, the average yield of corn was 380 bushels per hectare which is equals to 9655 kg per hectare. This increase in the productivity of corn crop is due to advancement of technology, high yielding seed varieties and reduces post harvest losses. The yield of 2008 is 17 times higher than 1964.
