Samantha and Michael are both training for a marathon. Samantha runs at a constant speed of 8 km/h, while Michael runs at a constant speed of 10 km/h. If Samantha starts her run 15 minutes before Michael, how long will it take Michael to catch up to Samantha, and how far will they have each run by then? Let's think step by step and output the final answer within \boxed{}.
