Just add 25 minutes. That's because they boarded at 3:55 and took 25 minutes to just go to the fair. So in 25 more minutes they got to the fair! so it would be 4:20 when they got to the fair.
Do:
3.55 - 0.25 - 1.15 = 2.15 hs
They arrived at fair the 2.15 hs
The Browns arrived at the fair at 2:15 PM. This is calculated by subtracting their travel time and the time spent at the fair from the boarding time. They boarded the train at 3:55 PM, traveled for 25 minutes, and spent 1 hour and 15 minutes at the fair.
