If film contain 4.4GB of data how long would it take to download by 2Mbps connection. give your answer in seconds and in scientific notation accurate to 2 decimal place? Please could you explain the figures as i really need to understand how to work this out, not just get the answer
4.4*10^9 Bytes of data is 3.52*10^10 bits of data. (1 Byte = 8 bits) Divide that by the bit rate of 2*10^6 bit/s and you get 1.76*10^4 seconds.
This is wrong above.When dealing with GB you have to use the 1024 multiples,not 1000. 4.4 GB is 4,774,464,025.6 bytes.
it should read something like:
4,774,464,025.6 / 2,000,000Mbps = 2362.3 * 8 = 18897.85 secs which is then:
1.89*10^4
Hope this helps
Sorry the figure is wrong above it should be:
4,774,464,025.6 / 2,000,000Mbps = 2387.23
To determine how long it would take to download a film with a size of 4.4GB using a 2Mbps (megabits per second) connection, we can use the following steps:
Step 1: Convert the file size from gigabytes (GB) to megabits (Mb):
1GB = 1024MB
1MB = 8Mb
Therefore, 4.4GB equals:
4.4 GB * 1024 MB/GB * 8 Mb/MB = 35,840 Mb
Step 2: Calculate the time it will take to download with a 2Mbps connection.
2Mbps means that 2 megabits of data can be transmitted in one second.
Time (in seconds) = Size (in bits) / Speed (in bits per second)
Time = 35,840 Mb / 2 Mbps
Resulting in:
Time = 35,840 Mb / 2 Mbps
Time = 35,840 Mb / (2 * 1,000,000 bits per second)
Time = 17.92 seconds
To express the answer in scientific notation accurate to 2 decimal places, we can write it as:
Time = 1.79 x 10^1 seconds
Therefore, the film would take approximately 1.79 x 10^1 seconds (or 17.92 seconds) to download using a 2Mbps connection.
