If I have done this right 1300m.Originally Posted by bharathlece
Now if you tell us what you have done on this and where you are having
difficulties you might get some help in how to solve this sort of problem.

A and B run in opposite directions from a pt. P on a circle with different but constant speeds. A runs in clockwise direction. They meet for the first time at a distance of 900 m in clockwise direction from P and for the second time at a distance of 800 m in anticlockwise direction from P. If B is yet to complete one round, the circumference of the circle is
a) 1700m b) 1250m c) 1300m d) 1200m

I TOUGHT TOTAL CIRCUMFERENCE OF CIRCLE IS X
1 ST A -> 900
B -> X-900
2ND A-> X-800
B-> 800
THEN WHAT TO DO HEAR IS MY DOUBT
PLZ SAY ANS IN BRIEF
Let the circumference be {math]C[/tex], and the two speeds beOriginally Posted by bharathlece
and , then when they meet for the
first time:
,
but we also know that:
,
and:
.
These three equations may be used to generate two equations which
do not contain :
.
Also when they meet for a second time:
,
but we also know that:
,
and:
.
These three equations may be used to generate two equations which
do not contain :
.
The value of can be easily found for these two sets of equations.
