Question 860273
Use the length formula for each part of th trip
City 1 to City 2:
{{{ d[1] = sqrt( ( 33 - 0 )^2 + ( 56 - 0 )^2 ) }}}
{{{ d[1] = sqrt( 33^2 + 56^2 ) }}}
{{{ d[1] = sqrt( 1089 + 3136 ) }}}
{{{ d[1] = sqrt( 4225 ) }}}
{{{  d[1] = 65 }}}
---------------------
City 2 to City 3
{{{ d[2] = sqrt( ( 33 - 23 )^2 + ( 56 - 32 )^2 ) }}}
{{{ d[2] = sqrt( 10^2 + 24^2 ) }}}
{{{ d[2] = sqrt( 100 + 576 ) }}}
{{{ d[2] = sqrt( 676 ) }}}
{{{ d[2] = 26 }}}
-----------------
{{{ d[1] + d[2] = 65 + 26 }}}
{{{ d[1] + d[2] = 91 }}}
