Question 1021378
<pre>
              rate         times             distances

Motor          20           m                  20m

Peddle         16           p                  16p

Total                       {{{6&1/2}}}                116
</pre>

{{{system(m+p=6&1/2,20m+16p=116)}}}



{{{system(m+p=6&1/2,20m+16p=116)}}}


Distance equation members divisible by 4:
{{{system(m+p=6&1/2,5m+4p=29)}}}
and then multiply the time equation's members by 4 to prepare for Elimination Method:
{{{system(4m+4p=26,5m+4p=29)}}}


Quickly find  {{{highlight_green(m=3)}}}.
The distance traveling motorized was {{{20m=20*3=highlight(60*miles)}}}.
