Rob is arranging two dental appointments, one with her dentist and one with the hygienist. To save travelling to the dental practice on two separate occasions, Rob would like to arrange them so that both of the sessions take place on the same day. The dental appointment will last for 45 minutes, the hygienist appointment will last for 20 minutes and there must be at least a 15 minute gap between the two sessions. With this in mind, which appointments should Rob select?
a. 10:45am Dentist and 11:40am Hygienist
b. 11:00am Dentist and 11:55am Hygienist
c. 11:45am Dentist and 12:10pm Hygienist
d. 1:45pm Dentist and 2:55pm Hygienist
e. 2:45pm Dentist and 3:35pm Hygienist

Answer:
the answer must be d. 1:45pm dentist and 2:55pm hygienist
Step-by-step explanation:
As mentioned in the question there should be a gap of 15 minutes in between Both the appointments ,and the dental appointment lasts for 45 minutes.
so the total gap between the starts of both appointments => 15+45=60 minutes (or) 1 hour.
By option verification,only option d has a time difference of more than 1 hour.
