Step 1: Look at the speeds given for each metal in the table. Step 2: Compare these speeds to find the highest one. The speeds are as follows:- Aluminum: 6420 m/s- Brass: 4700 m/s- Copper: 5010 m/s- Lead: 1960 m/sStep 3: Identify the metal with the highest speed.The highest speed is 6420 m/s, which corresponds to Aluminum.So, the sound waves will travel the fastest through Aluminum.Answer: C. Aluminum
