Answer:
Step-by-step explanation:
1. We know it travels 346 meters in a second, we now need to multiply 346 by 20. This equals 6920
2. Sound travels 5971 meters per second. We need to multiply this by 12 to find the distance it travels in 12 seconds. 71652 meters
3. We know sound travels 5971 meters per second in stone and 5000 meters per second from the chart. We need to find the difference between these and multiply that by 17 to find the distance covered in 17 seconds.
5971-5000=971
971*17=16507
Sound travels 16507 more meters in 17 seconds through stone than it would travel in aluminum
