Problem Statement

Eddie has a study block that lasts 11 hour. It takes Eddie 2525 minutes to do his homework and 55 minutes to play a game of Clash Royale. He can’t do both at the same time. How many games can he play in this study block while still completing his homework?
Proposed by Edwin Zhao
Solution. 7\boxed{7} Study block lasts 60 minutes, thus he has 35 minutes to play Clash Royale, during which he can play 355=7\frac{35}{5}=\boxed{7} games.
