how long can a reasonably fit person usually perform high - intensity activities?
about a minute
2 - 3 minutes
5 - 10 minutes
30 minutes
30 - 60 minutes

Explanation:

High - intensity activities are very demanding on the body. Even for a reasonably fit person, the body's energy systems and muscles fatigue quickly. The anaerobic energy systems that power high - intensity efforts can only sustain for a short time. Typically, a reasonably fit person can perform high - intensity activities for 2 - 3 minutes before significant fatigue sets in.

Answer:

B. 2 - 3 minutes
