If the time at Town A longitude 75 degrees west is 5 p.m. on Friday what will be the time at Town B longitude 120 degrees east
It's 5 a.m. Saturday.
The rough rule is that each hour covers about 15 degrees longitude.
To determine the time at Town B, which is located at a longitude of 120 degrees east, we'll need to consider the time difference between the two towns.
Longitude lines are divided into 360 degrees, with each degree representing 4 minutes of time difference. The time difference between two locations is calculated using the formula:
Time difference = (longitude difference / 15) * 60 minutes
In this case, the longitude difference between Town B (120 degrees east) and Town A (75 degrees west) is:
Longitude difference = 120 degrees (Town B) - (-75 degrees) (Town A)
= 120 degrees + 75 degrees
= 195 degrees
Now, using the formula mentioned above, let's calculate the time difference:
Time difference = (195 degrees / 15) * 60 minutes
= 13 * 60 minutes
= 780 minutes
Since 1 hour contains 60 minutes, we can divide the time difference by 60 to convert it into hours:
Time difference in hours = 780 minutes / 60
= 13 hours
Finally, to determine the time at Town B, we add the time difference to the time at Town A.
If it's 5 p.m. on Friday at Town A, adding 13 hours will give us the time at Town B:
5 p.m. + 13 hours = 6 p.m. (the following day)
Therefore, the time at Town B, located at a longitude of 120 degrees east, would be 6 p.m. on Saturday.
