Answer:
30 minutes.
Step-by-step explanation:
8:55 - 8:25 is 30 minutes.
If you add 30 to 8:25, you would get 8:55.
Therefore, it's 30 minutes.
The time taken for radio signal to the earth's surface we shall proceed as follows;
time=(distance)/(speed)
Distance=7.5×10^6 meters
speed=3×10^8 meters/second
therefore:
Time=(7.5×10^6)/(3×10^8)=0.025 seconds
We conclude that it will take the signal 0.025 seconds to reach the surface of the earth.
