Physics Question

Physics Homework.

Can someone please help me with this Physics?

For number one, it would be alright to calculate average speed because the slope of the line doesn't change, right?

I am lost on number two. I know it's asking for instantaneous speed and I have no idea how to find that. The book gives an example drawing a tangent line on a positive slope, but as you can see, object B is a negative slope, and I'm not even sure if that is the method I am supposed to perform anyway.

And because I am lost on number two, I am unable to complete the rest of the questions..
