Question

During an experiment,a single 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*108 m s-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

m/s

t= time taken =5min=5×60s=300s

∴s=3×10

×300=9×10
