Question

A nan shouted near a hills and heard the echo after 8 second . what is the distance of the hill from the man of the speed of sound is 345m/s​

Answer 1

1380 m is your answer

explaination:

TIME = 8S

SPEED = 345 ms

beacause of echo we will take it as 2d,

THEN WE KNOW THAT D = SPEED × TIME

THERFORE,2D=S×T

2d = 345 × 8

d= 345×8/2

HENCE,

d = 345 × 4

then,

d = 1380m
