1. A huge explosion is heard 73 kilometers away. How long does it take the sound to travel that far? (Assume ambient air temperature is 24 degrees C). Record your answer to the nearest whole second. No decimal places in your answer. Be careful of your units
2. Scientists in a laboratory produce a sound wave in a simulated environment (air) with a velocity of 487 m/s.What is the temperature (in Celsius) of the environment?
