Answer:
2.5 x miles
Step-by-step explanation:
We are given that 1 light year ≈ 5.9 x miles so:
- 4.3 x 10² light year · <u>5.9 x </u>
<u> miles </u>
- 1 light year
Multiply 4.3 an 5.9 and round to 2 significant digits then add the exponents:
≈25 x
This is not the scientific notation since the number is not between 0 and 10 so we move the decimal point by 1 place to the left. We then add 1 to the exponent to obtain the final answer:
≈ 2.5 x miles
Add the three numbers together and then divide 212.49÷60.49=3.51
