Question 1 of 5
1. Question
What time difference will `86°` of longitude make?Hint
Help VideoCorrect
Great Work!
Incorrect
Time difference can be solved by using only the degree of longitudeRemember that the Earth rotates `360°` in `24` hours.This means we can find how many minutes it takes to move `1°``360°` `=` `24` hours `360°``-:24` `=` `24` hours `-:24` Divide both sides by `24` `15°` `=` `1` hour `15°` `=` `60` minutes Convert hours to minutes `15°``-:15` `=` `60` minutes `-:15` Divide both sides by `15` `1°` `=` `4` minutes Hence, `1°` of longitude makes a time difference of `4` minutesNext, find the time difference with `86°` of longitude`1°` `=` `4` minutes `1°``xx86` `=` `4` minutes `xx86` Multiply `86` to both sides `86°` `=` `344` minutes `86°` `=` `5` hours `44` minutes `5` hours `44` minutes -

Incorrect
The prime meridian is a line of longitude at `0°`On the opposite side of the prime meridian lies the `180°` meridian.Finding the Time Difference
`1°` of longitude to the west `=` subtract 4 minutes (West = lest)`1°` of longitude to the east `=` add 4 minutes (East = beast)First, draw a rectangle with the Prime Meridian and the two longitudesSince both longitudes are to the east, draw the line for the Prime Meridian first
The prime meridian is also called Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC)Draw a line that connects the two longitudes
This line represents a minus sign, which means we must get the difference between the two longitudes`145°-97°` `=` `48°` Finally, solve for the time difference by multiplying `4``48°``xx4` `=` `192` minutes `=` `3` hours `12` minutes Hence, the time difference between `145°E` and `97°E` is `3` hours `12` minutes`3` hours `12` minutes -

`1°` of longitude to the west `=` subtract 4 minutes (West = lest)`1°` of longitude to the east `=` add 4 minutes (East = beast)First, draw a rectangle with the Prime Meridian and the two longitudesSince one longitude is to the west and the other is to the east, the Prime Meridian should be in the middle
The prime meridian is also called Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC)Draw a line that connects the two longitudes
This represents a plus sign, which means we must get the sum of the two longitudes`32°+27°` `=` `59°` Finally, solve for the time difference by multiplying `4``59°``xx4` `=` `236` minutes `=` `3` hours `56` minutes Hence, the time difference between `32°W` and `27°E` is `3` hours `56` minutes`3` hours `56` minutes -

`1°` of longitude to the west `=` subtract 4 minutes (West = lest)`1°` of longitude to the east `=` add 4 minutes (East = beast)First, draw a rectangle with the Prime Meridian and the two longitudes of each citySince both longitudes are to the east, draw the line for the Prime Meridian first
The prime meridian is also called Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC)Draw a line that connects the two longitudes
This line represents a minus sign, which means we must get the difference between the two longitudes`145°-28°` `=` `117°` Finally, solve for the time difference by multiplying `4``117°``xx4` `=` `468` minutes `=` `7` hours `48` minutes Hence, the time difference between Melbourne and Johannesburg is `7` hours `48` minutes`7` hours `48` minutes
