Question

A wheel makes 10 revolution per min. How many revolutions does it make per second?

Answer 1

To solve this problem, it is necessary to convert minutes to seconds and then re calculate the number of revolutions per second, this way:

`\frac{10\text{rev}}{\min }\cdot(1\min)/(60s)=(10rev)/(60s)`

Solve the division

`(10)/(60)(rev)/(s)=(1)/(6)\frac{\text{rev}}{s}=0.166(rev)/(s)`

The wheel makes 0.166 revolutions per second
