## anonymous one year ago A rail is 10 m long. It must be supported at least once every 3 m, beginning with a support at the far left end. Counting the first support, at how many points must a support be added to the rail? 2 points 3 points 4 points 5 points

It's 2 points. What do you think?

2. anonymous

If you took ten and separated it into groups of three, one would be left over. That's how I got my answer. :)
