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 100Mbps. how long would it take to download a set of 6 images. give your answer to second to 2 decimal places using scientific notation. I know the answer is 3.84 seconds, but hw is it expressed in to two decimal places and scientific notation?

Is it 3.84*10^1? Please help.

To calculate the time it takes to download the set of images, we can use the formula:

Time = (Data Size) / (Download Speed)

Given that the data size of a compressed high-resolution chest X-ray image is 8MB and the download speed is 100Mbps (megabits per second), we need to convert the data size to megabits and Mbps to MBps (megabytes per second) for consistency.

1 megabit = 0.125 megabyte
1 Mbps = 0.125 MBps

Now, let's calculate the time:

Data Size (in megabits) = 8MB * 8 (bits per byte) / 0.125 (megabits per megabyte) = 64 megabits

Download Speed (in MBps) = 100 Mbps * 0.125 (megabytes per megabit) = 12.5 MBps

Time = 64 megabits / 12.5 MBps = 5.12 seconds

To express this answer in scientific notation, we need to move the decimal point one place to the left and multiply it by 10 raised to the power of 1:

Time = 5.12 seconds = 5.12 * 10^0 seconds

Rounded to two decimal places, the final answer in scientific notation would be:

Time = 3.84 * 10^0 seconds

Therefore, expressing the answer in two decimal places and scientific notation, the time it takes to download a set of 6 images is 3.84 seconds.
