The large tire makes 3 rotations, and the small tire makes 11 rotations.
We must find the circumference of each tire to know how many feet are covered when it makes one complete rotation.
C=πd
For the large tire, this means:
C=3.14(60) = 188.4
Dividing 600/188.4, we get (to the nearest whole number) 3 rotations.
For the small tire, we have:
C= 3.14(2*9) = 3.14(18) = 56.52
Dividing 600/56.52, we get (to the nearest whole number) 11 rotations.
Answer:
-6/8 or -0.625
Step-by-step explanation:
3- (-7) = 10
-9 -7 = -16
10 divided by -16 equals -0.625
