Question

The distance from Venus to the sun is about 67,000,000 miles. The distance from Earth to the sun is about 2.6×10^7
farther. What is the distance from Earth to the sun? Write your answer in scientific notation to 1 decimal place.

Answer 1

To find the distance from Earth to the sun, you need to add the distance from Venus to the sun (67,000,000 miles) and the additional distance (2.6 × 10^7 miles).

First, we can express 67,000,000 miles in scientific notation:

\[
67,000,000 = 6.7 \times 10^7 \text{ miles}
\]

Next, we already have the distance from the sun to Earth in scientific notation:

\[
2.6 \times 10^7 \text{ miles}
\]

Now, add these two distances together:

\[
6.7 \times 10^7 + 2.6 \times 10^7 = (6.7 + 2.6) \times 10^7 = 9.3 \times 10^7 \text{ miles}
\]

Thus, the distance from Earth to the sun is:

\[
\boxed{9.3 \times 10^7} \text{ miles}
\]
