Answer:
t = 44.73 s
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,
![t=(d)/(v)\\\\t=(2000)/(44.704)\\\\t=44.73\ s](https://img.qammunity.org/2022/formulas/mathematics/high-school/ie1et49ve8ve1h0aclmfrsy3h7ua9v89c3.png)
So, it will take 44.73 seconds to reach 2 km.
