Generally speaking, running 50 meters a minute is normal, but there may be some differences for different people.
For adults, if they are in good health and have no obvious health problems, running 50 meters a minute is perfectly acceptable. This speed is equivalent to running 3 kilometers per hour, which is a relatively common speed for daily jogging or brisk walking. 
However, for some professional athletes or trained people, they may run faster. For these people, running 50 meters a minute can be a slower pace. In addition, the speed of running is also affected by many factors, such as age, gender, weight, muscle strength, cardiorespiratory fitness, exercise habits, and many more. If a person wants to improve their running speed, it can do so with proper training and improving their health. 
In short, running 50 meters a minute is a relatively normal running speed, but whether it is normal or not needs to be judged according to the individual's physical condition and exercise habits. If you have any questions or concerns about your running speed, it is recommended to consult a doctor or professional fitness trainer.
