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× 10m/s

Answer 2

We know that ,

Speed = Distance travelled/Time taken

Here ,

Speed = 3 × 10^8 m/s

Distance travelled = ? ( To be calculated )

And , Time taken = 5 minutes

= 5 × 60 seconds

= 300 seconds

Now , putting the values of speed and time in the above formula , we get :

=> 3 × 10^8 = Distance travelled/300

=> Distance travelled = 3 × 10^8 × 300 m

=> Distance travelled = 9 × 10^10 m

Thus , the distance of spaceship from the ground station is 9 × 10^10 metres.
