The mortality rate due to the roller skating is 10%

Step-by-step explanation:

Given:

Population of the city = 100,000

Number of skaters in Funville during any given month = 12,000

Roller-skating accidents in Funville = 600

Total number of residents injured from roller-skating = 1,800

number of deaths from roller-skating = 90

Total number of deaths from all causes = 900
