Hi everyone, this blog is about maths, this is the picture,
and these are some of the questions,
Using the image above, what is the ratio between the pedal gear and sprocket?
If you were to turn the crank 9 full rotations how many revolutions would the wheel do?
If one rotation of the pedal gear moves the bike 150cm, how far will the bike travel around the track if you did 5 full rotations of the pedal gear.
Thanks for looking at this blog, let me know if you can figure out these questions, bye.
Which gear ratio would you have to pedal more as you go once around the bike track - 4:1 or 2:1, what is your reasoning?
