The speed of light in a vacuum is 2.998 x 108 m/s. What is its speed in kilometers per hour (km/h) ? העתK speed = What is its speed in miles per minute (mi/min) ? speed = mi/min

Speed of light = 1.0793 * 10⁹ km/h

Speed of light = 1.115 * 10⁷ km/h

Explanation:

Given that:

The speed of the light = 2.998 * 10⁸ m/s

To find the speed of light in km/h

So,

1 m = 10⁻³ km

1 s = 1/3600 hr

So,

The speed of the light = (2.998 * 10⁸ * 10⁻³) * 3600 km/h

Speed of light = 1.0793 * 10⁹ km/h

To find the speed of light in mi/min

So,

1 m = 0.00062 miles

1 s = 1/60 min

So,

The speed of the light = (2.998 * 10⁸ * 0.00062) * 60 mi/min

Speed of light = 1.115 * 10⁷ km/h
