Well to get to 32 hours and knowing for all 4 days, she worked the same number of hours.
All we have to do is multiply all these numbers by 4 to see which one is equal to 32.
6 * 4 = 28
10 * 4 = 40
8 * 4 = 32
4 * 4 = 16

48.8 megabytes. When the download is 17.5% complete, have been downloaded 48.8 megabytes.
The key to solve this problem is using the rule of three.
If 279Mb -------------> 100%
x <------------- 17.5%
x = [(279 megabytes)(17.5)]/100
x = 48.825 megabytes
Round to the nearest tenth 48.8 megabytes.
(192/16)*4.55*1.43 = 39039/500 =78.078
