Answer:
The wheels have to rotate 500 times
Step-by-step explanation:
The wheel is 1 meter in diameter so we need to find the circumference.
C = 2
r
C = 2
1
C= 2
2meters = .002kilometers
1000meters = 1kilometer
1000/2 = 500
1/3times3=3/3 3/3 is the same as a whole so do 41 and 1/2 times 3 this gets you an answer of 124.5 meaning the unit 124.5x he makes 124.5 rotations per minute
it had to be b cuz now all quadrilateral have straight sides
