To find out how many miles are in \(3.52 \times 10^7\) meters, using the conversion that \(1 \text{ mile} \approx 1.6 \times 10^3 \text{ m}\), we can set up the following calculation:
- First, we divide the total meters by the number of meters in a mile:
\[ \text{Number of miles} = \frac{3.52 \times 10^7 \text{ m}}{1.6 \times 10^3 \text{ m/mile}} \]
- Performing the division:
\[ \text{Number of miles} = \frac{3.52}{1.6} \times \frac{10^7}{10^3} \]
- Calculating \(\frac{3.52}{1.6}\):
\[ \frac{3.52}{1.6} = 2.2 \]
- Calculating \(\frac{10^7}{10^3}\):
\[ \frac{10^7}{10^3} = 10^{7-3} = 10^4 \]
- Combining these results gives:
\[ \text{Number of miles} = 2.2 \times 10^4 \]
So, the final answer is:
\[ \boxed{2.2 \times 10^4} \text{ miles} \]
