The audio cable is 1.61m long.
Step - by - Step Explanation
What to find? Length of cable in meter.
Given:
Length = 16.1 dm
To convert 16.1dm to m;
Let x be the length of the audio cable in meter.
Using proportion,
1 m = 10 dm
x = 16.1 dm
Cross -multiply
10x = 16.1
Divide both-side of the equation by 10.

x = 1.61m
Hence, the length of the audio cable in meters is 1.61m
