Question 1164837
.
Mark left town P for town Q at 10am, travelling at a uniform speed of 75km/h. 
Jane left town P for town Q an hour after Mark, travelling at 120km/h. 
She passed Mark after travelling 2/5 of the journey. she reached town Q at 4 pm. 
How far was Jane from town Q when she passed Mark?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
When Jane left town P for town Q at 11 am, Mark was 75 km ahead.

The difference of their speeds is 120 - 75 = 45 km/h.


Hence, Jane passed Mark in  {{{75/45}}} = {{{5/3}}} hours, counting from 11 am.


During this time,  {{{5/3}}}  hours, Jane covered the distance of  {{{120*(5/3)}}} = 40*5 = 200 km.


This distance, 200 km, is  {{{2/5}}}  of the distance from P to Q, according to the problem.


Hence, the whole distance from P to Q is  {{{(5/2)*200}}} = 500 km.


From the other side, Jane traveled 5 hours (from 11 am to 4 pm) at the speed of 120 km/h -
hence, she traveled 5*120 = 600 km.


Thus we obtained two different values, 500 km and 600 km, for the distance from P to Q.


It tells us that the different parts of the problem are not consistent.

Thus, the problem is SELF-CONTRADICTORY, is posed INCORRECTLY and MAKES NO sense.
