why does a telephone makes sound travel faster than sound
Telephone calls are made using an electrical signal that travels at the speed of light in a vacuum. This is much slower than the speed at which sound waves can travel, which is around 340 meters per second (about 700 kilometers per hour). However, the extra distance that the signal needs to travel through the air due to the sounds being transmitted also means that the signals arrive at their destination slightly delayed compared to if they had traveled at the faster speed of sound. This delay is what causes the ring of a phone to seem quieter when you're talking on it compared to when someone else is trying to call you.
