The expression that would be shown would be:
![(50mi)/(hr)*(1hr)/(60min)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/o6abqovfdhqwpbescw676netyvt0pj162s.png)
Then we would simply multiply across to make the correct conversion, while also canceling out units that are found on both the top and the bottom of the fraction bars:
![(50mi)/(hr)*(1hr)/(60min)=(0.833mi)/(min)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/zato364y7e7pmty07yss4rgawt4v00r13p.png)
So now we know that 50mph can be converted to 0.833 miles per minute.
