    3 s.

    Explanation:

    Echo is defined as the repetition of a sound produced by the reflection of sound waves from an obstructing surface like a wall, mountain etc.

    v = f*lambda

    Where,

    Lambda = wavelength of the wave

    f = frequency of the wave = 1/t

    v = velocity of the wave.

    Distance there and back = initial ditance * 2

    = 525 x 2

    = 1050.

    Time taken, t = lamda/velocity

    = 1050 / 350

    = 3 s.

    So the delay is 3 seconds.
