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.
