Answer:
3 hours
Step-by-step explanation:
Since Connie has been washing for an hour already, 9 of the windows have been washed, thus, there are 48 windows left. Together, Connie and Rick wash 16 windows per hour, and thus, together, it takes them 3 more hours to finish the job. Thus, Rick works 3 hours
