. If the fastest passenger aircraft can fly 0.45 km/s (1000 mph), how long would it take to reach the sun? The galactic center?

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The passenger aircraft would take years to reach the gallactic center.

Explanation:

The distance to the sun from the Earth is approximately equal to , if the passenger travels at constant speed, then the time needed to reach the sun is calculated by the following kinematic formula:

(1)

Where:

- Travelled distance, measured in kilometers.

- Speed of the passenger aircraft, measured in kilometers per second.

- Travelling time, measured in seconds.

If we know that and , then the travelling time is:

The passenger aircraft would take 10.542 years to reach the Sun from the Earth.

The distance between the Earth and the galactic center is approximately equal to . If the passenger travels at constant speed and if we know that and , then the travelling time is:

The passenger aircraft would take years to reach the gallactic center.
