A) 680 m
B) 1700 m
C) 340 m
D) 1620 m
Correct Answer: C
Solution :
Let the distance between the two cliffs be\[d\]. Since, the man is standing midway between the two cliffs, then the distance of man from either end is\[d/2\]. The distance travelled by sound (in producing an echo) \[2\times \frac{d}{2}=v\times t\] \[\Rightarrow \] \[d=340\times 1=340\,m\]You need to login to perform this action.
