1)A compressed high resolution chest xray image requires about 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 images. give your answer to second to 2 decimal places.

2)as a part of pilot project some surgeries at distance have connection at 100 Mbps. how long would it take one of these surgeries to download the same image.

8MB/image * 6 images = 48 MB total

48 MB * (1 second/2 MB) = 24 seconds

In part 2 the transmission is 100/2 or 50 times as fast

8MB/image * 6 images = 48 MB total

48 MB * (8 Mb/MB) * (1 second/2 Mb) = 192 seconds

In part 2 the transmission is 100/2 or 50 times as fast

This looks very much like the question I answered yesterday. That one had no part 2.

I agree with Damon's answer.

What is the answer to part two??

I mean in Scientific notation?

To calculate the time it would take to download the images, we need to consider the file size, network speed, and conversion of units. Let's break down the calculation step by step:

1) For a GP surgery connected to the NHS network at a speed of 2 Mbps:
a) First, we need to convert the file size from MB to megabits (Mb) since network speeds are usually measured in bits per second.
8 MB = 8 * 8 = 64 megabits (Mb)

b) Next, we calculate the time it would take to download one image:
Time = File Size / Network Speed
Time = 64 Mb / 2 Mbps
Time = 32 seconds

c) Since there are 6 images to download, we multiply the time by the number of images:
Total Time = Time per Image * Number of Images
Total Time = 32 seconds * 6
Total Time = 192 seconds (or 3 minutes and 12 seconds)

Therefore, it would take 192 seconds (3 minutes and 12 seconds) to download a set of 6 images at a speed of 2 Mbps.

2) For surgeries with a connection speed of 100 Mbps:
a) Following the same steps as above, we calculate the time it would take to download one image:
Time = 64 Mb / 100 Mbps
Time = 0.64 seconds

b) Since there are 6 images to download, we multiply the time by the number of images:
Total Time = Time per Image * Number of Images
Total Time = 0.64 seconds * 6
Total Time = 3.84 seconds

Therefore, it would take approximately 3.84 seconds to download a set of 6 images at a speed of 100 Mbps for surgeries with this connection.
