When we convert units, we have to use a conversion factor, which is a fraction of the relation between the magnitudes involved. In this case, if we want to convert 1.3 hours to minutes, we have to multiply by 60min / 1h because in the opposite case, we won't obtain the correct transformation. The expression below shows it.
[tex]1.3hr\cdot\frac{1hr}{60\min}=0.02166\ldots\frac{hr^2}{\min }[/tex]As you can observe, we are not able to convert the units following the given statement.
