30 min: 60min-30min= 30 min and 30 min is half an hour. So since 30 min is half an hour you divide 4 by 2 and get 2 miles.
45 min: 60min-45min= 15 min. 15 is one quarter of an hour so, since you are going 4mph. So you do 4mph divided by another for because there are four quarters in one hour, which gives you one mile. Then you 1 mile 3 times because 15+15+15=45. So the answer is 3 miles.
2 hours: 2x4= 8 miles
3 hours: 3 hours x 4mph= 12 miles
Answer:
9 1/4
Step-by-step explanation:
1/2 = 2/4
11 1/2 = 11 2/4
11 2/4 - 2 1/4
11 - 2 = 9
2/4 - 1/4 = 1/4
9 1/4

Using the Fundamental Counting Theorem, we have that:
4. 1,757,600 different license plates can be there.
5. 676,000,000 different driver's license numbers can be formed.
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with ways to be done, each thing independent of the other, the number of ways they can be done is:
For the letters there are 26 outcomes and for the digits there are 10 outcomes, hence the parameters for item 4 are given as follows:
Hence the number of license plates is given by:
N = 26 x 26 x 10 x 10 x 26 = 1,757,600.
For item 5, the parameters are:
Hence the number of license numbers is:
26 x 26 x 10 x 10 x 10 x 10 x 10 x 10 = 676,000,000
