Question

I need to know How many weeks will the man be in dimensional analysis with correct scientific notation, significant figures and units.

Answer 1

We know that the man is 45 years old on August 27 and we are interested in determine the number of weeks. So we can do the following conversion:

$45\text{years}\cdot\frac{52weeks}{1year}=2340weeks=2.34x10^3weeks$

We assume that for this case a year have 52 weeks
