You took a train trip to visit your cousin. By 10:15 the train had traveled 20 mi. By 10:30 the train had traveled an additional 10 mi. You are now halfway to your cousin’s town. At what time will you reach your cousin’s town if the train’s speed is constant?

in 15 minutes, this train travels 10 mi, then the train starts at 9:45. It takes 45 minutes to be halfway. So it will takes another 45 minutes from 10:30. So the answer is 11:15
