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?
Answers
B travelled half of 800 m on his first meeting with A who had travelled 900 m
900 + 400 = 1300.
hence circumference of circle is 1300m.
thank you
Answer:
The final answer is 1300.
Step-by-step explanation:
Given,
A and B are running in opposite directions in a circle at different yet constant speeds. A runs in clockwise direction so B automatically runs in anti clockwise direction. Both of them start from a point p in the circle.
They first meet at a point 900m in the clockwise direction away from P.
Their second meeting is at a point 800m in the anti clockwise direction away from P.
Also we are told that B is yet to complete one round the circle.
Since both A and B are running in constant speeds this would mean that B managed to completed 400m between the two meetings.
Then, The total circumference of the circle will be 900+ 400 = 1300.
