Question

4. The distance light travels in one year is approximately 5,870,000,000,000 miles. The distance light travels in 100 years is:

(a) 587 × 108 miles, (b) 587 × 1010 miles, (c) 587 × 10-10 miles, (d) 587 × 1012 miles, (e) 587 × 10-12 miles

Answer 1

Solution:

The distance of the light travels in 100 years is:

5,870,000,000,000 × 100 miles.

= 587,000,000,000,000 miles.

= 587 × 1012 miles.

Answer: (d)

Answer 2

Option (d)
`\(587 * 10^(12)\)` miles is the correct answer for the distance light travels in 100 years based on the given distance for one year.

The distance light travels in one year, often referred to as a light-year, is approximately
`\(5,870,000,000,000\)` miles.

To find the distance light travels in 100 years, you can multiply the one-year distance by 100. The correct answer is (d)
`\(587 * 10^(12)\)` miles.

The reasoning is as follows:
`\[ \text{Distance in 100 years} = \text{Distance in one year} * 100 = 5,870,000,000,000 \, \text{miles} * 100 = 587 * 10^(12) \, \text{miles}. \]`

Therefore, option (d)
`\(587 * 10^(12)\)` miles is the correct answer for the distance light travels in 100 years based on the given distance for one year.
