The answer is C because is n is positive and even it will only open up.
Here 'a' corresponds to 0.
Now there are two possibilities for 'r' & 't'
Case 1.
They are on the same side to the right of 'a'
In that case 'r' corresponds to 5 & 't' corresponds to 7.
The midpoint of 'r' and 't' shall be 
Case 2.
Both are on the left of 'a'.
In that case 'r' corresponds to -5 & 't' corresponds to -7
The midpoint shall be 
Case 3.
'r' in on the right of 'a' and 't' is on the left of 'a'
So 'r' corresponds to 5 and 't' corresponds to -7
The midpoint shall be 
Case 4.
'r' is on the left of 'a' & 't' is on the right of 'a'.
'r' corresponds to -5 & 't' corresponds to 7
The midpoint shall be 
The possible coordinates of the midpoints of rt are 6, -6, 1, -1.

Answer:
The ship arrived at 5 am on Saturday
Step-by-step explanation:
Here, we want to know at what time and day the ship arrive the second port
we simply need to add the time it left the first port and the amount of time the journey took
Mathematically, that will be;
22:45 + 7 1/4
1/4 is same as 60/4 = 15 minutes
So we have;
22:45 + 7:15
= 5 am on Saturday
