The front gear on the bike has 32 teeth and the rear, on the wheel, has 12 teeth. How many times does the bike's rear-wheel turn if you turn the right pedal 30 times? What distance will you go if the circumference of the bicycle wheel is 250 cm?

Correct answer:

n2 =  80
s =  200 m

Step-by-step explanation:

s1=s2 n2 12=32 30 n2=1232 30=80
o=250 cm m=250:100  m=2.5 m  s=o n2=2.5 80=200 m
