In 1970, a farmer using a two-row combine with a corn head could easily harvest 0.75 ha (1.85 acres) per hour and a typical corn
Anastaziya [24]

Answer:

The value is w = 6.7 \%

Step-by-step explanation:

Generally the productivity rate is mathematically represented as

P_r =  K  * Z

Here K is the ha the farmer could harvest in an hour and Z is a typical yield of corn in kg/ha

Now considering 1970

The productivity rate is

P_r =  0.75   *5000

=> P_r =  3750 \  kg/h

Now considering 1940

The productivity rate is given as P_R =  250 \ kg/h

Generally the productivity ratio is mathematically ration is mathematically represented as

w =  \frac{P_R}{P_r}  * 100

=> w =  \frac{250}{3750}  * 100

=> w = 6.7 \%
