Question 460642
The equation for the freight train is:
(1) {{{ x = 30t }}}
The equation for the express train is:
(2) {{{ x + 300 = 55t }}}
-------------------
Both trains will travel for {{{ t }}} hrs, but the
express train has to go 300 mi further
(2) {{{ x = 55t - 300 }}}
{{{ 30t = 55t - 300 }}}
{{{ 25t = 300 }}}
{{{ t = 12 }}}
It will take 12 hrs to catch freight train
The express train travels {{{ x+ 300 }}} mi
