If you give the clues I could help.
Answer:
The wheel have made
revolutions.
Step-by-step explanation:
The total distance traveled during the race is
D = 4510km [(1000m)/(1km)] = 
The radius (r1) of the smaller bicycle wheel is
r1 = 
Than the larger wheel has a radius
r2 = 0.329 m + 0.012 m = 0.341 m
Over the same distance this wheel would make N2 revolutions
N2 =
