Answer:
(a) Yes
(b) No
(c) No
Explanation:
(a) Yes
Due to the fact that the monk started at both the journeys at the same time, and completed both journeys at the same time, there is a likelihood that the monk was at the middle of the journey at about the same time of half the journey's duration
(b) Where the monk started the journey back at 5 AM and completed, got back at 9 AM, then it is unlikely that the monk would ave been at the same time because the distance covered per unit time is different while the starting time is the same
(c) Here we have the the start time as 10 AM and the arrival at the seaside monastery at 3 PM, therefore, to answer the question, we assume another monk start from the seaside monastery at 5 AM on a journey to the mpnstery at the top of the mountain, to arrive there by 11 AM, since the time difference for both journeys are
11 AM - 5 AM = 6 Hours and
3 PM - 10 AM = 5 Hours
The midpoint of the journey will therefore be reached at different times by the two monks
Time to mid point for monk 1 = 6/2 or 3 hours
Time to mid point for monk 2 = 5/2 or 2.5 hours.
