The answer is- The speed of light in vacuum = .[tex]1.1153 *10^7\ mi/min[/tex].
Speed : The rate of change of the object's position in any direction. It's about how fast the object is moving. A higher speed means the object is moving faster. Lower speed means it moves slower. If it is at rest, it has zero speed.
What is the formula to calculate speed of a substance ?
- Speed is the distance travelled per the time taken to cover that distance.
- It is calculated as- [tex]Speed =\frac{Distance\ travelled}{Time\ taken\ to\ cover\ that\ distance} =\frac{d}{t}[/tex]
- Now, the given speed of light in vacuum is [tex]2.9983*10^8[/tex] m/s. To convert this in miles/min, the following relations must be used-
[tex]1\ m = 0.00062\ miles[/tex]
and [tex]1 s = \frac{1}{60}\ min[/tex]
Therefore, the speed in mi/min is converted as-
[tex]Speed =\frac{ (2.9983 *10^8 m/s) *(0.00062 mi/m)}{\frac{1}{60}\ min/s } = 1.1153*10^7 mi/min[/tex]
Hence, the speed of light in mi/min = [tex]1.1153 *10^7\ mi/min[/tex].
