Question

What is the time taken for a radio signal to travel from Edinburgh to London, covering a distance of 600 kilometers? Choose the closest time from the following options:

A) 0.001 seconds
B) 0.01 seconds
C) 0.1 seconds
D) 1 second

Answer 1

The approximate time taken for a radio signal to travel 600 kilometers is 0.002 seconds, but the closest answer provided is 0.01 seconds, which is option B.

Step-by-step explanation:

The time taken for a radio signal to travel from Edinburgh to London, covering a distance of 600 kilometers, depends on the speed at which the signal travels. Radio signals travel at the speed of light, which is approximately 299,792 kilometers per second. To calculate the time taken for the radio signal to cover 600 kilometers, we can use the formula time = distance/speed. This calculation would result in a time of approximately 0.002 seconds. However, since this option is not available, we choose the closest time which is Option B) 0.01 seconds.

Relying on our knowledge of Physics, we understand that electromagnetic waves such as light or radio signals travel extremely fast, thus the travel time over terrestrial distances like between cities on Earth is very short and often measurable in milliseconds or microseconds.
