Answer:

60 sec.

Step-by-step explanation:

The first person has to travel 200m at 2 m/s. It will take him 200/2=100 seconds to reach the gate. The second person is moving towards the gate at 2 + 3 meters per second so it will take her 200/5 = 40 seconds to reach the gate. Therefore, person #1 needs an extra 100-40 = 60 seconds.
