Question 1180129
The time is strictly given as 1 hour.  The distance of travel and speed are variables.


{{{v*x=d}}}


{{{v=d/x}}}
The MAXIMUM speed was stated, 45 mph.
{{{d/x<=45}}}
but x was already given as 1 hour.  This then is NOT a variable.  The only outcome for the description is {{{d<=45}}}.
