The distance between two cities, A and B, is 60 miles. Matthew left city A and he is riding a bicycle to city B at a speed of 12mph. AJ left city A one hour later than Matthew and is riding his bicycle to city B as well at a speed of 15mph. AJ stopped for a 30 minutes rest.
Who will get to city B earlier and how much earlier? Draw a model and show your work.
