Detailed Solution
Download Solution PDFGiven:
Circular track length = 840 m
Speed of A = 6 m/s
Speed of B = 12 m/s
Formula used:
Time to meet = Track length / Relative speed
Relative speed (since they are running in the same direction) = Speed of B - Speed of A
Calculation:
Relative speed = 12 m/s - 6 m/s = 6 m/s
Time to meet = 840 m / 6 m/s
⇒ Time to meet = 140 seconds
∴ A and B will meet next after 140 seconds.
