The guru of a yogi lives in a Himalyan cave, 1000 km away from the house of the yogi . The yogi claims that whenever he thinks about his guru, the guru immediately knows about it. Calcualte the minimum possible tiem interval between the yogi thinking about the guru and the guru knowing about it.

Explanation

Here `S = 1000 km = 10^(6) m `
The process requires minimum possible time if the velocity is maximum. We know that maximum velocity can be that of light (i.e. `3xx 10^(8) m /s)`
` Time = Distance / Speed `
` = 10^(6) / 3 xx 10^(8) = 1 /300 s `
