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 \times 10^8 \text{ m s}^{-1}.
Answer
Given:
Speed of signal (v) = 3 \times 10^8 \text{ m/s}
Time taken (t) = 5 \text{ min} = 5 \times 60 = 300 \text{ s}
Formula:
\text{Distance} = \text{Speed} \times \text{Time}
Calculation:
= (3 \times 10^8 \text{ m/s}) \times 300 \text{ s}= 900 \times 10^8 \text{ m}= 9 \times 10^{10} \text{ m}
Answer: The distance of the spaceship from the ground station is 9 \times 10^{10} \text{ m}.
