Longitude and time TC5228ARTC

LONGITUDES AND TIME

In this article I'll show you the simplest way of calculating time of different places in the world.

Qn # 1:

When it 8 am GMT what will be the time in East Africa?

Solution

Before you start, you have to know the longitudinal location of each place given in the question. From our question:

The longitude for GMT is 0°

The longitude for East Africa is 45° E

Step 1:

difference in longitude = 45° – 0° = 45°

Step 2:

Convert the difference obtained in step 1 into time:

1° = 4 minutes then,

45° = 45° x 4 minutes = 180 minutes = 3:00 hours.

Now we have difference in time which is 3:00 hours.

Either we take (i)  8:00 – 3:00 or 8:00 + 3:00

Which operation is required above?

You have to know where you find the time of. From our question we need the time of East Africa.

Step #3

Simply draw their longitudes to locate and come up with the following method:

After location, use your left hand fingers such as index and middle fingers to find out what operation is required. Simply write addition sign(+) on the ridge of middle finger and subtraction  sign(-) on the ridge of index finger as shown below:

Then put your hand below the illustration to find out what operation is required as shown below:

From our illustration above we need the time of East Africa and our finger shows addition operation

Step # 4

So the Last step is to apply the operation:

8:00 + 3:00 = 11:00

From 8 am to 11:00 also will be a.m because it is still morning

More questions to come................ be patient
