Question

If you average 3.00 revolutions of the bicycle pedals every 2.00 seconds how far does the bike travel per unit of time

Answer 1

Hello! Let's solve it using Rule of Three:

considering unit of time = 1 minute

`\begin{gathered} \frac{2\text{ sec}}{60\text{ sec}}=\frac{3\text{ revolutions}}{x\text{ revolutions}} \\ \\ 2\cdot x=60\cdot3 \\ 2x=180 \\ x=(180)/(2) \\ x=90\text{ revolutions} \end{gathered}`

So, the bike will travel 90 revolutions per minute.
