Anjali and Babita are running on a circular track in opposite directions from same time at same point with speeds of 8 m/sec and 6 m/sec, respectively. If the length of the circular track is 960 m, how many times distinct points they will meet?
Explanation:
Number of disting meetings points for two people whose simplified ratio of speeds is a : b is ⇒ (a + b), when going in opposite directions ⇒ |a - b|, when going in same direction
Ratio of speed of Anajli and Babita = 8 : 6 = 4 : 3.
∴ Number of distinct points on the circle where they will meet = 4 + 3 = 7.
Hence, option (a).
