It is obviously one hour+ so:

3/0.2=15

60 minutes/15=4 minutes

One hour & four minutes!

You can use the units to help you

$$\\\not{km}\times \frac{hours}{\not{km}}=hours\\ so\\ \not{km}\div \frac{\not{km}}{hours}=hours\\ so\\ 3.3\not{km}\div \frac{3\not{km}}{hours}=3.2\div 3 hours\\ that's\\ 1.0\bar6\;\;hours \\ and\\ 0.0\bar6\;\;hour=0.1\times 60 =4\;\;minutes\\ So that is \\ 1 hour and 4 minutes$$\$
