In Sec 3 WB page 38, Ex 1, #d: "She explained that she was hoping..." Why do you use the continuous tense here? I think the simple would be better?

This is an exercise in which students have to read the reported speech and write what the people said. Here, the person explained, "I'm hoping to come and see you next week."
With the verb hope, we use the present continuous to say that we are depending on something happening. (See LDOCE) That meaning fits the verb explain that is used here. She is not just saying that she hopes (wants) to come and visit, but that she is depending on that visit for something. We are not told what that something is. Perhaps she needs to get something from the person or give the person something.
