To estimate how long it would take to fly a jet to the Sun from Earth, let's consider the average distance from Earth to the Sun, which is about 93 million miles (or about 150 million kilometers).
Assuming a typical jet airliner speed of about 500 miles per hour (approximately 800 kilometers per hour), we can calculate the travel time:
- Distance to the Sun: 93,000,000 miles
- Speed of the jet: 500 miles per hour
Using the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
Calculating the time:
\[ \text{Time} = \frac{93,000,000 \text{ miles}}{500 \text{ miles/hour}} = 186,000 \text{ hours} \]
To convert hours into years:
\[ 186,000 \text{ hours} \div 24 \text{ hours/day} \approx 7,750 \text{ days} \]
\[ 7,750 \text{ days} \div 365 \text{ days/year} \approx 21.16 \text{ years} \]
So, it would take approximately 21 years to fly a jet to the Sun, which is not one of the options listed. However, the closest answer to the calculated time is 18 years.
Therefore, the best choice from the options is 18 years.
