Answer:
12
Step-by-step explanation:
Answer:
P43=4!(4–3)!=241=24
Step-by-step explanation:
There are four choices you can make for the lead reindeer. For each possible choice, there are then three remaining you can choose to fly second, making 4×3=12 choices for the lead pair. For each possible choice there are two remaining reindeer to take up the back position, making 12×2=24 choices for the team of three.
This type of problem is called a permutation problem, and we write Pnr for the number of ways of choosing r items from n possibilities when the order of the items matters. In this case we are choosing 3 reindeer from 4 possibilities, and the order they appear in the flying line does matter, so the answer we want is P43. The general formula is Pnr=n!(n−r)!. For the answer we are looking for we therefore have:
P43=4!(4–3)!=241=24
Answer:
211.75 miles
Step-by-step explanation:
121 miles = 2 hours
divide both sides by two to get the distance per hour
60.5 miles = 1 hour
multiply both sides by 3.5 to figure out the distance
60.5 (3.5) = 1 (3.5)
211.75 miles = 3.5 hours
