Question 129616
Let {{{d}}}= the distance apart
Let {{{t}}}= her actual time
{{{d = 32t}}}
{{{d = 36(t - .5)}}}
{{{32t = 36(t - .5)}}}
{{{32t = 36t - 18}}}
{{{4t = 18}}}
{{{t = 4.5}}}
{{{d = 32*t}}}
{{{d = 32*4.5}}}
{{{d = 144}}}mi
The towns are 144 mi apart
check answer:
{{{d = 32t}}}
{{{d = 36(t - .5)}}}
{{{144 = 32t}}}
{{{t = 4.5}}}
{{{144 = 36t - 18}}}
{{{36t = 162}}}
{{{t = 4.5}}}
OK
