Question

Ellen planned to interview some applicants for a position in her office. If she scheduled 1/4 of an hour to meet each of them, how much time did she schedule for all 6 applicants?

Answer 1

1/4hr=1applicant
?= 6applicants
1/4*6
6/4
1/1/2
60mins +30mins=90mins
1hr=60mins
? =90mins
90/60=3/2
1hr 30mins or 1/1/2 hrs

Answer 2

1/4 of an hour = 25 min.
6 * 25min. = 150min

1 hour = 60 min.
150min. / 60min = 2.5 Hours

Therefore Ellen would have had to schedule 2 hours and 30min to meet all the applicants.
