Given that,
A remote car makes 2 revolutions in 20 seconds.
We need to find the period of the object.
It means, it will make [tex]\dfrac{2}{20}=0.1\ \text{revolutions/second}[/tex] .
lt T be the period of the object. So,
[tex]T=\dfrac{1}{0.1}\\\\T=10\ s[/tex]
It will take 10 seconds for one revolution.
