Answer 1

Answer:

5:00pm

75 X 4=300 min

300min= 5hrs

Answer 2

the Prime meridian is 0 degree and to the west side we subtract and to the east we add. 1 degree is equal to 4 minutes so multiply the longitudes value with 4 that gives us the value in minutes. we divide the value in minutes to obtain the time in hours (and minutes) .then we calculate the time by adding or subtracting the value from the time at the Prime meridian which depends on if the value for the longitude is east or west .

the answer is 5 pm.
