Question 1030933
.
Wendy traveled 300 km. She traveled part of the way (a distance of x km) by and bus and arrived at the train station 
just in time to complete her journey by train. The average speed of the bus was 40 km per hour and on average the train 
travelled 20 km per hour faster than the bus. The entire trip took 5 and 1/2 hours. Which equation can be used to solve for x?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Time by the bus    {{{x/40}}}        hours    (distance/speed).

Time by the train  {{{(300-x)/(40+20)}}}  hours    (distance/speed).

In total

{{{x/40}}} + {{{(300-x)/60}}} = {{{5}}}{{{1/2}}}.

This is the equation to solve and find the distance x under the question.
