Answer:
The Grand Canyon is 3,536 m (11,591 ft) deep at the given spot.
Explanation:
The Grand Canyon is around 1,904 m (6,200 ft) deep at its deepest point, making the speed of sound 340 m/s. To calculate the depth of the canyon at a spot where we can hear our echo 5.2 seconds after we shout, we need to multiply the speed of sound by the time it takes for the sound to travel down and back.
The time it takes for the sound to travel down and back is 10.4 seconds (5.2 seconds down and 5.2 seconds back). This means the sound is travelling a total of 3,536 meters (11,591 ft). This concludes that the Grand Canyon is 3,536 m (11,591 ft) deep at the given spot.
