Step-by-step explanation:
given diameter of wheels (d) = 50 cm
radius (r) = (d/2)= (50/2)= 25 cm
given revolutions per minute of the wheels of the cycle (N) = 420
therefore revolutions per sec = (420/60)
(N) = 7
angular velocity (w) = 2*π*N
= (2)*(22/7)*7
w = 44 rad/sec
linear speed of the wheels of cycle
= (r) *( w)
= (25) * (44)
= 1100 cm/sec
= 11 m/s
