Answer 2

Radius (r) = 50cm

Perimeter = 2πr=2x 3.14x50=314cm

Speed of Cycling = 10km/hr

= 10x1000 m/hr

=10000 m/hr

Time required = Perimeter speed of cycling

------------------------------------------

Speed of cycling

= 3.14hr

----------

10000

= 3.14 X 3600

--------------------

10000

= 1.1304 seconds.
