Ryan and Janelle are each driving from a different location to meet. When they each stopped for lunch at 12 noon, they called each other on their cell phones. Ryan had traveled miles in 3 hours. Janelle had driven miles in 4 hours.

If Ryan and Janelle were originally miles apart when they had started driving that morning, at what time will they meet? Homework Help ✎
