Question

Marissa is standing on a at the edge of a canyon. She yells loudly and hears an echo 1.6 s later. How far away is the other side of the canyon? You may assume the speed of sound is 340 m/s.

Answer 1

Answer:

other side is 272 m is far away

Explanation:

given data

sound speed = 340 m/s

time = 1.6 s

to find out

How far away is the other side

solution

we know here sound is first go strike and then return so

total time taken in going and coming journey is 1.6 s

so distance will be 2x

so we apply here distance formula

distance = speed × time

put value

2x = 340 × 1.6

x = 544 / 2

x = 272

so distance = 272 m

hence we say other side is 272 m is far away

Answer 2

Answer:

The distance of other side of the canyon is 272 m.

Explanation:

Given that,

Time = 1.6 s

Speed = 340 m/s

We need to calculate the distance

Using formula of distance

$v = \dfrac{2d}{t}$

$d=\dfrac{v\times t}{2}$

Where, v = speed

t = time

d = distance

Put the value into the formula

$d=\dfrac{340\times1.6}{2}$

$d=272\ m$

Hence, The distance of other side of the canyon is 272 m.
