Question

During an experiment, a signal from a spaceship reached the ground station in five minutes.what was the distance of the space ship from the ground station? The signal of travels with speed of light

Answer 1

Time=5*60=300 s Speed=3*100000000 m/s Distance =speed *time = 3*3*10^10 =90000000000m =90000000km
