Rather than teaching you how you'd convert this particular question, I would like to teach you how to convert quantities with any arbitrary dimensions.
Consider, your problem
1) convert each of those units into the other, for e.g. 1mi= 1.6km, 1hr=60min.
2)Plug them in directly: 45 mi/h =#{45\times1.6}/60 {km}/{min} #=#1.2{km}/{min}#.
There's you answer, just convert each of those units to the other, and directly plug them in, and you get your answer.
