A compressed high-resolution chest xray image requires 8MB of data. most GP surgeries are connected to the NHS network at a speed of 2Mbps. how long would it take to download a set of 6 image. give your answer to seconds, to two decimal places using scientific notation.

6 * 8 *10^6 bytes/ (2*10^6 bits/s * 1 byte/8 bits)= 1.92*10^2 s.

6*8MB = 48

48MB*1024*1024 = 50331648 B

50331648*8 = 402653184 bits

402653184/2000000 (Mbps) = 201.326592

2.01 to two decimal points (2.01*10^2)seconds.
