Each of the measurements below describes length. rank them from longest length to shortest length.
1mi, 10m, 1x10^11nm, and 50in.

In order to rank these measurements correctly, it would be useful to convert the values to the same units. For this case, we convert them to meters. We do as follows:

1mi = 1609.34 m
10m = 10 m
1x10^11nm = 100 m
50in = 1.27 m

Therefore, the correct ranking would be as follows:

1mi, 1x10^11nm, 10m, and 50in.
