Answer:

t = 44.73 s

Step-by-step explanation:

Given that,

The speed of a sound wave, v = 100 mph = 44.704 m/s

We need to find the time taken by the shockwave to reach 2 km i.e. 2000 m

We know that,

Speed = distance/time

So,

[tex]t=\dfrac{d}{v}\\\\t=\dfrac{2000}{44.704}\\\\t=44.73\ s[/tex]

So, it will take 44.73 seconds to reach 2 km.
