Taking the speed of the radio signal as 3×108 m/s, calculate the time taken for a signal to reach a GPS receiver from a GPS satellite at a position 21 000 km distant from the receiver. Assume that the speed of the signal is unchanged over the whole path length. Express your answer in milliseconds

simono860s
total distance=21000km=21000000m
time=distance/speed
       =21000000/(3x108)
       =0.07s
       =70milliseconds
