Ответ:
1 × 10^10 years
Explanation:
The current distance of the Moon from the Earth = 400,000 km
Every year, the Moon moves: 40 millimeters away from the Earth
From the question:
1 millimeter = 1 x 10^-6 kilometers
40 millimeters =
= 40 ×1 × 10^-6km
= 4 × 10^-5km
= 0.00004km
In approximately how many years will the moon be twice as far from the Earth as it is now, assuming that nothing else changes?
Twice as far = 400,000km × 2
= 800,000km
0.00004km = 1 year
400000km =
= 400,000km/0.00004km
= 10000000000years
= 1 × 10^10 years
