Light takes 4 hours to cover the distance from Sun to Neptune. If you travel in a spaceship at a speed 0.99c (where c is the speed of light in vacuum), the time (in minutes) required to cover the same distance measured with a clock on the spaceship will

Answer:
It will show 33.86 minutes.
Explanation:
Here, what we take into concern is Time dilation.
It is a consequence of Einstein's general theory of relativity.
According to this, one experiences lesser time if he/she moves at a relative speed with something.
Now, as per your question, the formula for velocity time dilation goes like-
\frac{T'}{T}=\sqrt{1-\frac{v^2}{c^2}}
T

where,
T' is the time in frame of moving body,
T is time in frame of relative rest,
v is velocity of the moving body, and
c is the speed of light.
Now, if we solve this for v = 0.99c, we get
T' = 0.1411 T
that is,
T' ≈ 33.86 minutes ≈ 33 minutes 51 seconds
