Answer:
The 12 students can be lined up in 12! ways.
Put in dividers after every fourth student.
For example:
Given ABCDEFGHIJKL, we would put in dividers to get ABCD|EFGH|IJKL.
We have overcounted, though, in two different ways. Let's examine the resulting problems.
One problem is with regard to the three separate groupings appearing multiple times. In the example above, we would be counting EFGH|ABCD|IJKL a second time. Since there are three groups, we need to divide by 3! to avoid this sort of overcounting.
The second problem is that, within each of the three groups, we have four people who are going to appear multiple times. In the example above, we would be counting CDAB|EFGH|IJKL a second time. For each of the groupings, we need to divide by 4! to avoid this sort of overcounting. This means dividing by 4!4!4! to amelioriate the second issue.
Then our answer becomes:
12!3!4!4!4!=5,775

47mph and 32 kph
The ratio is 1.6kph for every 1mph so for the first one you divide by 1.6 and the second you multiply
