Net Force, Motion graphs and Calculating Speed

Jorge stays after class to work on is science homework and is late for hockey practice. He decides to run so the coach won't be mad. If the locker room is 300 m from the classroom and Jorge can run a surprising 25 m/s, how long would it take him to get there? 

• 10 s
• 14 m
• 12s
• 12 m/s
