Question

5. 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 to the power 8
ms-1​

Answer 1

Answer:

time=5 min =5×60=300 sec

speed=3×10^8 ms^-1

distance = time×speed

= 300×3×10^8

= 9×10^10 m

Answer 2

Answer:

9×10 ^10

m

Explanation:

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

8

×300=9×10 ^

10

m
