apart on the same road. Aurora starts walking at 3 mph and at the same instant Chris starts walking toward her at 2.2 mph. When will they meet. I just need to know how to set it up.|||I assume you mean they live 4 miles apart, and that they are in a straight-line path to each other.
You can think of this as Aurora is not moving, and Chris is moving towards her at 5.2 mph.
4 miles / 5.2 mph = 10 / 13 hours
