The important equation here is D = RT, distance = rate*time.
Emma travels for twenty minutes at 18 mph before Shane leaves, and thus covers six miles in that time. At 7:20, they are 44 miles apart. They approach each other at a combined rate of 41 mph, so they travel for 44/41 hours until they meet. So Emma travels for 44/41 + 1/3 hours and Shane travels for just 44/41 hours.
