In an early test of sound propagation through the ocean, an underwater explosion of 1 pound of dynamite in the Bahamas was detected 3200 km away on the coast of Africa. How much time elapsed between the explosion and the detection?

The time is 2133.3 sec.

Explanation:

Given that,

Distance = 3200 km

We know that,

The sound velocity in seawater is 1500 m/s.

We need to calculate the time

Using formula of velocity

Where, t = time

v = velocity

d = distance

Put the value into the formula

Hence, The time is 2133.3 sec.
