It is obviously one hour+ so:

3/0.2=15

60 minutes/15=4 minutes

One hour & four minutes!

How long would it take to walk 3.2 km at 3 km per hour (?) It would take 1hr and 4 min.

You can use the units to help you

$$\\\not{km}\times \frac{hours}{\not{km}}=hours\\

so\\

\not{km}\div \frac{\not{km}}{hours}=hours\\

so\\

3.3\not{km}\div \frac{3\not{km}}{hours}=3.2\div 3 hours\\

that's\\

1.0\bar6\;\;hours \\

and\\

0.0\bar6\;\;hour=0.1\times 60 =4\;\;minutes\\

$So that is$ \\

$1 hour and 4 minutes$$$
