PROBLEM FOR WORKSHOP

All right math workshop people here's a problem that we will probably have in class or will be on my dad's website later

After how many more kilometres will this happen again?

Math Kangaroo Workshop at Cornerstone

Hello this is post especially for people in my dad's workshop (math kangaroo at Cornerstone if you go there I've probably told you about this site). I know my dad already has a website but this blog will also be posting math problems and things. So I would suggest to look here often if you want a heads up on our homework if there is any, lessons that we will be studying, and also suggestions for my dad's workshop. SO PLEASE POST if you want to :D.
