Let the time taken be 'x' hours.

Angie can process the payroll in 5 hours. so in x hours, she can process x/5 of the payroll

Pam can process the payroll in 6 hours. so in x hours, Pam can process x/6 of the payroll

The fraction that Angie process the payroll  in x hours +The fraction that Pam process the payroll  in x hours = 1 payroll processed

x/5 + x/6 =1

11x/30 =1

11x=30

x =30/11

=2.72 hours
