Answer:
1.6 ft
Step-by-step explanation:
Each time the wheel does a complete turn, the bike moves forward a distance equal to the wheel's circumference. Since the bike moves 200 ft after 40 rotations, the length of the wheel's circumference is:
C = 200 ft / 40
C = 5 ft
Circumference is π times the diameter. So the diameter of the wheel is:
C = πd
5 ft = πd
d = 1.6 ft
