Question 903980
Think of this as one truck standing still
and the other one moving at the sum
of their speeds toward the other
{{{ 180 = ( 65 + 55 )*t }}}
{{{ t = 180 / 120 }}}
{{{ t = 3/2 }}}
---------------
NY to Albany truck:
{{{ d[1] = 65*(3/2) }}}
{{{ d[1] = 97.5 }}} mi
--------------------
Albany to NY truck:
{{{ d[2] = 55*(3/2) }}}
{{{ d[2] = 82.5 }}} mi
----------------
check:
{{{ d[1] + d[2] = 97.5 + 82.5 }}}
{{{ d[1] + d[2] = 180 }}}
OK
