Q1 of 58 Page 37

During an experiment, a signal from a spaceship reached the ground station in five seconds. What was the distance of the spaceship from the ground station? The signal travels at the speed of light that is 3 × 108 m/s

Given: speed of signal = m/s

Time is taken by signal to reach the ground = 5s


Distance = speed time


= (m/s) 5 (s)


= m
