A and B are running around a 40 km circle at respective speeds of 16 kmph and 20 kmph. The number of distinct meeting points for A and B when they run in same direction is x and when they run in opposite directions is y. Find x + y
Explanation:
When the simplified ratio of speed of two people running around a circle is a : b
No. of distinct meeting points when they run in:
(i) same direction = |a - b|
(ii) opposite direction = a + b
Here, simplified ratio of speeds in the given question = 16 : 20 = 4 : 5.
∴ x = 1 and y = 9
Hence, 10.
