How much time elapses before the geologist hears sound

Reference no: EM13705568

Compute each part of given question:

Question: A geologist is camped 4,873 m (about 3 miles) from a volcano as it erupts.

Part A: How much time elapses before the geologist hears the sound from the eruption? (Assume the air temperature is 20°C.)

Part B: How much time does it take the seismic waves produced by the eruption to reach the geologist's camp, assuming the waves travel along the surface through granite as sound waves do? (Assume the granite temperature is 20°C.)

Don't just give me the answer; explain your steps as well.
