Understanding Circuits: Calculating Velocity at 25.5 km/h

I was looking on a resource to help explain to me the concept of circuits.. Then realized that it's almost as if my teacher has plagiarized from this site for his lesson plan.. Anyhow, just going over the old lessons of the site..

How do they calculate the velocity to be 25.5 km/h? Simple mistake, I'm hoping?

Oh yeah..

That site..

simple mistake indeed.

you mean why is it 25.5 instead of 25? I think that's clearly a mistake unless I'm not catching something

Just making sure.. Wonder why they would have a mistake like that for a 10 year old site.
