Answer:

0.0163 s

Step-by-step explanation:

Distance traveled = 3040 mi

1 mile = 1609.34 m

Distance traveled = 3040 x 1609.34

Distance traveled = 4892406 m

Speed = 300,000,000 m/s

Time = Distance/Speed

Time = 4892406/300000000

Time = 0.0163 s

Therefore, it will take a telephone signal approximately 0.0163 s to travel 3040 mi from coast to coast across the United States
