Represent this situation graphically and find whether the two trains meet each other at some place.

He can row 12 km downstream and 12 km upstream in 4 hours. EMF certainly includes problems but under a different pedagogical philosophy: To use the EMF Help Forum, students must obey strict rules including rules prohibiting the request or provision of answers and the use of inappropriate language.

Students are also expected to take a long time puzzling through the more difficult problems, often by putting pencil to paper, and without giving up too quickly.

How can I get more information. Now, the length of table is Y axis and breadth is X axis. The solutions given for the exercises in this chapter will help the student to move ahead and understand the concepts of Coordinate Geometry.
