Answer 1

Answer:

the answer is 5×60×3 into 10 power 8

5 minutes

60 seconds

3x10^8 velocity of light

Answer 2

Answer:

9×10

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

Then, S=vt

where, v= speed of signal =3×10

8

m/s

t= time taken =5min=5×60s=300s

∴s=3×10

×300=9×10
