Part A: Using a writing speed of 800 Mbits/s, how long would it take to store a 40 GB raw video file on blue ray disk? How small would the 40 GB raw video file become if it is compressed with a compression ratio of 8. Part B: Taking the speed of the radio signal as 3×100 meters per second, calculate the time taken for a signal to reach a GPS receiver from a GPS satellite at a position 20000 km distant from the receiver. Assume that the speed of the signal is unchanged over the whole path length. Expres your answer in milliseconds.
