{{{drawing(300,300,-20,150,-10,90,grid(1),
circle(5,28,2),
circle(25,35,2),
circle(48,44,2),
circle(76,51,2))}}}

Using EXCEL regression, best fit line is {{{T=0.3285t+26.855}}}
So when {{{t=136}}}, {{{T=71.5}}}
{{{drawing(300,300,-20,150,-10,90,grid(1),
circle(5,28,2),
circle(25,35,2),
circle(48,44,2),
circle(76,51,2),
circle(136,71.5,2),
graph(300,300,-20,150,-10,90,0.3285x+26.855))}}}
