Question 110789
Knowing that {{{electricity }}}{{{travels}}} at approximately {{{one }}}{{{foot }}}{{{per }}}{{{1.5}}}{{{ nanoseconds}}} , we can write it as:

{{{1ft/1.5ns}}}



Since one {{{foot=0.000189394ml}}} and {{{1.5 _nanoseconds=0.0000015ms}}}, we have:

electricity travels at  {{{0.000189394ml /0.0000015ms}}}

Now we need to see how far electricity travels in 7ms: 


{{{(0.000189394ml /0.0000015ms)*7ms}}}.....cancel {{{ms}}}
{{{0.001325758ml/0.0000015=883.84ml}}}
