How many light minutes is the Earth away from Mercury?

Since light travels at a speed of 300,000 km/sec, one minute will cover 300,000 x 60 = 18000000. Dividing 77000000 by 18000000 yields 4.27 light minutes.

The distance between Earth and Mercury varies, ranging from approximately 77 million kilometers to 222 million kilometers. On average, it's around 91 million kilometers. This corresponds to about 8.19 light minutes.

The average distance between Earth and Mercury is approximately 77 million kilometers (48 million miles). Light travels at a speed of about 299,792 kilometers per second (186,282 miles per second). Therefore, the time it takes for light to travel from Mercury to Earth (or vice versa) can be calculated by dividing the distance by the speed of light.

( \frac{77,000,000 , \text{km}}{299,792 , \text{km/s}} \approx 257.1 , \text{s} )

To convert seconds to minutes, divide by 60:

( \frac{257.1 , \text{s}}{60} \approx 4.285 , \text{min} )

So, the Earth is approximately 4.285 light minutes away from Mercury.
