sound like yu hav a big klok with a arm (? minut arm?) that go round

diameter=135 meters

rim leng=pi*diam=3.14159265*135

=424.1150078 meter

speed av tip av hand=angular speed (omega)*radius=0.26 meter/sek

radius=135/2=67.5

omega=0.26/67.5=0.0038518 radians/sekond

1 time around=2pi radians

time=6.2831853/0.0038518

=1631.234 sekonds

round tu 1631 seks or 27.187 minuts
