Yoki is running a 10 mile race. She runs at a steady speed and then slows down, stops to get a drink of water, and then runs fast to get back in the race. Which graph represents the situation?

Answer:
D
Step-by-step explanation:
I believe the answer would be D because the graph shows a steady pace, then a slow-down and stop, and finally a sprint. (I could be wrong, and if I am, somebody please correct me.)
