The moon is approximately 400,000 kilometers from Earth. The moon gets approximately 40 millimeters farther away from the earth every year. 1 millimeter is 1 x 10^-6 kilometers. In approximately how many years will the moon be twice as far from the Earth as it is now, assuming that nothing else changes?

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

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
