Question 823870
{{{A=1*2^m}}}  m in minutes, A is amount of flowers, assuming initially 1 flower.  This is exponential growth but ignoring the continuousness of the growth.


Full basket after 60 minutes = 1 hour;
{{{A=1*2^60}}}, a very large number.


Find m when {{{A=(1/2)2^60}}}.
{{{(1/2)2^60=2^m}}}
{{{ln(1/2)+ln(2^60)=m*ln(2)}}}
{{{ln(1/2)+60*ln(2)=m*ln(2)}}}
{{{-0.693+60*0.693=m*0.693}}}
{{{0.693(60-1)=0.693*m}}}
{{{highlight(59=m)}}}------------fifty-nine minutes
