Instead of 1/4 an hour ellen spent 1/3 of an hour to meet each applicant how much more time did she spend meeting all applicants

5 more minutes (total of 20 minutes per applicant)

Step-by-step explanation:

Divide an hour by 1/3 (60/3 = 20 minutes)

Divide an hour by 1/4 (60/4 = 15 minutes)

By spending 1/3 of an hour (20 minutes) instead of 1/4 of an hour (15 minutes), she spent 5 more minutes meeting all applicants.
