Question

How many minutes are there in 4 years? (1 year = 52 weeks)

Answer 1

using the conversion factor,

`\begin{gathered} 1\text{ }year\Rightarrow52\text{ }weeks \\ 1\text{ }week\Rightarrow7\text{ }days \\ 1\text{ }day\Rightarrow24\text{ }hours \\ 1\text{ }hour\Rightarrow60\text{ }minutes \end{gathered}`

then, we multiply them together,

`4\text{ }years*\frac{52\text{ }weeks}{1\text{ }year}*\frac{7\text{ }days}{1\text{ }week}*\frac{24\text{ }hours}{1\text{ }day}*\frac{60\text{ }minutes}{1\text{ }hour}=2,096,640\text{ }minutes`
