If Juan had a doctor's appointment on a certain day, was the appointment on a Wednesday?
1) Exactly 60 hours before the appointment, it was Monday.
2) The appointment was between 1:00 pm and 9:00 pm.
Thanks! Please let me know if it is on Wednesday what time it would occur.
i think the answer is C
1) tells us prior to appt, 60 hrs = 2.5 days -> it was Monday
picking arbitrary times
Monday @ 12am = appt was on Wednesday @ noon
Monday @ 10pm = appt happened on Thursday @ 10am
not sufficient
2) appt was between 1pm and 9pm
only tells us the block of time appt occurred and not the day
not sufficient
putting 1) and 2) together, 60 hrs prior to Wed 1pm and 9pm
Monday @ 1am + 60 hrs = Wed @ 1pm
Monday @ 9am + 60 hrs = Wed @ 9pm
So using both statements we know that appt was on Wed
