Question 1159014
1, the amount of land grazed
n, original cattle quantity
r, graze rate for one cow
365, original graze time
x, the unknown graze time in days for the question condition


{{{rn*365=1}}}


For the question, {{{2n*r*x=1/2}}}


{{{nr*x=1/4}}}
Divide this equation by the original equation,
{{{x/365=1/4}}}

{{{x=365/4}}}


Between 91 and 92 days, closer to 91 days





(calculated 91.25)
