I don't think you can factor this.
Answer:
k = 12
Step-by-step explanation:
The constant of proportionality k is the ratio
k = 
Use any ordered pair from the table to find k
Using number of laps = 240, number of swimmers = 20 , then
k = 
= 12
5mn is the simplified answer
Answer:
Any multiple of 10
Step-by-step explanation:
A factor is defined as "a number or quantity that when multiplied with another produces a given number or expression." For example, the factors of 20 are 1, 2, 4, 5, 10, and 20.
When we multiply 2 and 5 together, we get 10. Multiplying this by anything else besides 0 will still yield something that has 2 and 5 as factors, for example 2 times 5 times 3 is 30. As this is just the same thing as multiplying 10 by 3, the answer is any multiple of 10.
