Question

An audio cable is 14.9dm long. How long is the cable in meters?Be sure to include the correct unit in your answer.

Answer 1

To answer the question we need to remember that the "d" before the meters measn denotes a factor of a tenth, that is:

`d=10^(-1)`

Hence we have:

`14.9dm=14.9*10^(-1)m=1.49m`

Therefore, the cable is 1.49 m long
