"The smart number should be divisible by 9 and 3.
The simplest choice is 19 miles for this distance."

19? Is this a typo? The equation uses 18 as the smart number, and 18 is divisible by both 9 and 3.


Any assistance with this would be greatly appreciated. =)

Hey Jlo,

Yes, it should say 19. You can see that they correct it when they actually move to solve. Silly typos!
