Answer:
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.
