Answer 1

Answer:

mark me as a brainliest

Explanation:

Let distance of hill from the position of the body be d.

Echo is heard after 6s

Speed of sound, v=340m/s

So, d=v×t/2  

d=340*6/2

=1020m

Answer 2

Answer:

hey mate here is the answer

Explanation:

cliff = 2d

v= 340 m/s

t = 6s

distance = speed × time

2d = v×t = 340× 6

or

d= 340 × 6/2 = 1020 is correct answer
