I answered a very similar question to your a couple of days ago, just follow the same steps

trains a&B are traveling in the same direction on parallel tracks. train a is traveling at 60 miles per hour and train b is traveling at 70 miles per hour. train a passes a station at 3:15a.m. if train b passes a station at 3:45a.m., what time will train b catch up to train a?
is there an equation to solve this. if so what equation would i use?
