Question

During an experiment, a signal
from a spaceship reached the
ground station in five minutes.
What was the distance of the
spaceship from the ground
'station? The signal travels at the
speed of light, that is, 3 x 10^8
ms-1​

Answer 1

Let the distance between the spaceship and the ground station be 'S' .

Then,

S=vt

where,

v= speed of signal

=3×10 8 m/st

= time taken

=5min=5×60s=

300s∴

s=3×10 8 ×300

=9×10¹⁰ m

Answer 2

Answer:

Let the distance between the spaceship and the ground station be 'S' .

Then, S=vt

where, v= speed of signal =3×10 ^8m/s

t= time taken =5min=5×60s=300s

∴s=3×10^8×300=9×10^10m
