It should take her father four hours to reach her.
Step-by-step explanation:
Since Madison takes an hour to travel 10 miles, by the time she reaches 3 hours, shes at 30 miles. (At this point her father has begun traveling towards her) And since he goes 15 miles per hour, four hours later (for her father), they will both be at the same distance.
(So in 6 hours, Madison goes 60 miles, and in 4 hours her father also goes 60 miles since hes faster)
Please tell me if I did anything wrong!
