Sir/madam, could you help me to solve below question? i need to solve it..
A jogger runs from her home to a point A, which is 6 km away. For those 6 km,she begins by running at a constant speed until she reaches a hilly portion 2 km from her home. Here, her speed slows down while she runs up the hill, which is a 1 km run. Then she speeds up while running down the hill. The last 2 km of the run are again at constant speed. Draw a graph to show the jogger's speed as a function of the distance from her home and find the range of this function.

I tried this:
Explanation:
Have a look:
I also assumed that the speed changes uniformly over the hill in B and C (if it is not uniform the line would be a curved one).
