She runs down the first a distance of 35.0 m at a speed of 3.50m/s. The second haallway is filled with students and she covers its 48.0 m lenght at an average speed of 1.20m/s. The final hallway is empty and She sprigs its 60.0 m at a speed of 5.00m/s.

distance = rate x time
35.0m = 3.50 m/s x time
Solve for time
Do the same for the other three halls and add the seconds (time) together to find total time. Add that to starting time to determine if she is early, on time, or late.
