The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.</span>
An eclipse i’m pretty sure right? Lunar maybe?
We know that:
speed = distance / time
time = distance / speed
The speed of light is 3 x 10⁸ m/s
Now, we must convert the distance to meters to obtain our answer in seconds. After that, we will multiply it by 1000 to obtain the answer in milliseconds(ms)
1 mile = 5280 ft
2462 miles = 2462 x 5280 = 12999360 ft
1 ft = 12 inches
12999360 ft = 12999360 x 12 = 155992320 in
1 in = 2.54 cm
155992320 in = 155992320 x 2.54 = 396220492.8 cm
1 m = 100 cm
396220492.8/100 = 3962204.928 m
Time = 3962204.928 / 3 x 10⁸
= 0.0132 seconds
1 s = 1000 ms
0.0132 x 1000 = 13.2 ms
