A and B run on a circular path of perimeter 1200 m at different speeds. If they start at the same time and from the same place but run in opposite directions, they meet for the first time in 3 minutes. If the speed of B is 10.8 km/h, then what is the speed (in km/h) of A?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 13.2.
Total distance covered when meeting = 1200 m
Combined speed = 1200/180 = 20/3 m/s
A's speed = (20/3) - 3 = 13.2 km/h
