Question

Hans stands at the rim of the Grand Canyon and yodels down to the bottom. He hears his yodel back from the canyon floor 5.20 s later. Assume that the speed of sound in air is 340.0 m/s. How deep is the canyon?

Answer 1

Answer:

1768m

Step-by-step explanation:

s=340

t=5.2

d=s*t

d=340x5.2

d=1768m

Answer 2

Answer:

884 m

Step-by-step explanation:

Distance is Speed *time

However depth is half of the distance

Hence, depth is given by

$= \frac{340 \times 5.2}{2} = 884m$
