Question 1034777
The bike rolls the length of it's wheel's
circumference with 1 revolution.
{{{ C = 2*pi*r }}}
and
{{{ d = 2r }}}
{{{ d = 1 }}} m
{{{ C = 1*pi }}}
The bike travels in a straight line
{{{ 132*pi }}} m/min
---------------------
Convert [m/min] to [km/hr]
[m/min] x [km/m] x [min/hr]
{{{ ( 132*pi )*( 1/1000 )*( 60/1 ) }}}
{{{ ( 132*pi )*( 6/100 ) }}}
{{{ 1.32*pi*6 = 7.92*pi }}}
{{{ 7.92*pi = 24.8814 }}}
His speed is 24.881 km/hr
