Anupam and Vineet standing together started running in opposite direction on 2 km long circular racing track. They ran at the speeds of 9 km/h and 11 km/h respectively. After how much time will they meet on the track?

Correct option is A

Given:

Length of circular track = 2 km
Speed of Anupam = 9 km/h
Speed of Vineet = 11 km/h
They run in opposite directions.

Formula Used:
Time = $$\frac{\text{Distance}}{\text{Speed}_1 + \text{Speed}_2}$$​​

Solution:
Relative speed = 9 + 11 = 20 km/h
Distance = 2 km

Time = $$\frac{2 }{ 20} =\frac{ 1}{10}$$ hours =$$\frac{1}{10}\times 60 =$$​ 6 minutes
