1st:Begin to assemble Phase Work for a quiz on Friday. We will review tomorrow and do quiz notes.
2,5,6: Does a mountain bike really have 21 gears?
Let’s assume that a mountain bike has the following numbers of teeth on the front and back:
Front 30, 40, 50 teeth
Back 11, 13, 15, 18, 21, 25, 30
Using the information we talked about in class today compare the 21 ratios of the gears and decide if the bicycle has 21 distinct gears.
