0.017s

Explanation:

Given parameter

Distance = 5000km = 5 x 10⁶m

Unknown:

time taken = ?

Solution:

We use the normal speed equation to solve this problem as we take the speed of the wave to be 3 x 10⁸m/s.

   Speed = \frac{Distance }{Time taken}

   Inputting the parameters:

             Time taken = \frac{distance }{velocity of the wave}

  Time taken = \frac{ 5 000000}{3 00000000} = 0.017s
