L-type seismic waves propagate from the epicenter at a speed of 4 km / s. How far will these waves travel in 20 s?
| June 15, 2021 | education
To calculate the distance traveled by the seismic wave from the epicenter, we apply the formula: S = V * t.
Values of variables: V – seismic wave propagation speed (V = 4 km / h); t – wave propagation time (t = 20 s).
Let’s calculate: S = V * t = 4 * 20 = 80 km.
Answer: B) In 20 s, the seismic wave will propagate 80 km from the epicenter.
