Question 951009
{{{ 80 }}} km/hr = ( {{{ 80 }}} km ) / ( {{{ 1 }}} hr )
The units of the ratio are:
[ km ] / [ hr ] = [ km ] / [ hr ]
{{{ 80 / 1 = 527 / t }}}
where {{{ t }}} is in hrs
----------------------------
Multiply both sides by {{{ 1*t }}}
{{{ 80t = 5278 }}}
{{{ t = 65.975 }}}
and
{{{ .975*60 = 58.5 }}}
and
{{{ .5*60 = 30 }}}
---------------------
It will take 65 hrs 58 min 30 sec
