Light is faster than sound!
Two people, A & B are standing on a perfectly flat surface at some distance from each other and facing each other. B shouts out "hello" to A. If A "heard" B one second after he "saw him shouting(his mouth moving)", what is the distance between them in meters? (Round off your answer to the nearest integer)
Assume: 1.A can see and hear B clearly no matter how large the distance between them gets. 2.Speed of light= 3 x (10^8)m/s. 3.Speed of sound=340m/s.
The answer is 340.
