Question

Do the math: How many seconds would it take an echo sounder’s ping to make the trip from a ship to the Challenger Deep (10,994 meters) and back? Recall that depth in meters = ½ (1500 m/sec × Echo travel time in seconds). Round your answer to two decimal places.

    Answer:

    14.66secs

    Explanation:

    Given the formula for calculating the depth in metres expressed as

    depth in meters = ½ (1500 m/sec × Echo travel time in seconds)

    Given depth of the challenger = 10, 994 meters, we will substitute this given value into the formula given to calculate the time take for the echo to travel.

    10, 994 = depth in meters = ½ * 1500 m/sec × Echo travel time in seconds

    10,994 = 750 * Echo travel time in seconds

    Dividing both sides by 750;

    Echo travel time in seconds = 10,994 /750

    Echo travel time in seconds ≈ 14.66secs (to two decimal places)

    Therefore, it would take an echo sounder’s ping 14.66secs to make the trip from a ship to the Challenger Deep and back
