### Question 12

12. In the table, a positive number shows how many hours the time location in ahead of the time in London, England. A negative number shows how many hours the time is behind the time in London.

*First of all: remember that in adding and subtracting fractions, you must find a common denominator first (if needed).

a) How many hours is the time in St. John's ahead of the time in Brandon?

To find the answer, I subtracted the amount of time in Brandon from the amount of
time in St. Johns. A diagram below shows you how I solved it, and therefore the time in St. John's is 2 and 1/2 hours ahead of the time in Brandon.

b) How many hours is the time in Victoria behind the time in Mumbai?
The process in the same as the last question, I subtracted the time in Victoria from the one in Mumbai. Below, it shows that time in Victoria is 13 and a half hours behind from that of Mumbai.

c) Determine and interpret the time difference between Tokyo and Kathmandu.
Once again, I subtracted the two times of both places. The diagram below shows that Tokyo is 3 and 1/4 hours ahead of Kathmandu.

d) Determine and interpret the time difference between Chatham Islands and St. John's.
I subtracted the amount of time in Chatham Islands to that of St. John's. The diagram below will show that Chatham Islands is 16 and 1/4 hours ahead.

e) In which location is the time exactly halfway between the times in Istanbul and Alice Springs?
The time in Kathmandu, Nepal is halfway between times in the other two locations. How did I know that? Because I added the times in Istanbul and Alice Springs (refer to chart above) and then I divided their sum by 2 because we are finding the halfway point. (Half= 2)
