Tyra is training for a bicycle race. each week she rides a total distance greater than 10 km and less than or equal to 30 km. if the distance is always an even number and a multiple of 3, what are the possible distances tyra rides in one week?

Our distance is x
We know each week she rides a total distance greater than 10 km and less than or equal to 30 km
We can write this like the following:
x > 10
x <= 30

It also tells us the distance is always an even number and a multiple of 3. Ask your self, what are some numbers between 10 and 30 and is a multiple of 3.

12, 18, 24 and 30

So the possible distances are 12, 18, 24, 30 

Notice each number is an even number and you can divide the number by 3 evenly so they are numbers with 3 being a multiple.
